Computer programming involves writing code to give computers instructions. An algorithm is a set of steps to solve a problem or complete a task. It takes inputs and produces outputs. Algorithms can be expressed using pseudocode, flowcharts, or programming languages. Pseudocode and flowcharts allow visualizing the steps in an informal way before writing actual code. Computer languages include low-level assembly languages close to machine code, and high-level languages like Python and Java that are easier for humans to read and write.
The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”.
flowchart is a type of diagram that represents an algorithm, workflow or process.
Computer programs contain instructions that tell computers what to do. Programs are written using programming languages as computers only understand machine code. There are different types of programming languages including machine language, assembly language, and high-level languages. High-level languages are easier for humans to read but must be compiled into machine code for computers to execute. Programming involves defining a problem, describing inputs and outputs, developing an algorithmic solution, and testing the program.
The document discusses algorithms and flowcharts. It defines an algorithm as an ordered sequence of steps to solve a problem and notes that algorithms go through problem solving and implementation phases. Pseudocode is used to develop algorithms, which are then represented visually using flowcharts. The document outlines common flowchart symbols and provides examples of algorithms and corresponding flowcharts to calculate grades, convert between units of length, and calculate an area. It also discusses complexity analysis of algorithms in terms of time and space.
An algorithm is a set of steps to solve a problem. Algorithms should be developed before building computer programs to solve problems. There are typically four basic steps: 1) analyze the problem, 2) design an algorithm solution, 3) write the program based on the algorithm, 4) test the program. Pseudocode uses plain English and some programming syntax to represent algorithms. Flowcharts use graphical symbols to represent algorithm steps and logic visually.
The document discusses algorithms, providing definitions and examples of algorithms including Euclid's algorithm for computing the greatest common divisor. It also outlines properties that algorithms must have including finiteness, absence of ambiguity, defined sequence and inputs/outputs. Pseudocode is introduced as a way to express algorithms at a high level for human reading using basic logic structures like sequence, selection, and iteration.
This document provides an introduction to the C programming language. It discusses the brief history of C, including its origins in the early 1970s at Bell Labs and its popularity due to its portability and efficiency. C is a structured, procedural programming language that is still widely used today for operating systems development and other software. The document outlines some key characteristics of C programs, such as their modular structure, support for both low-level and high-level language features, use of functions and pointers, and small size.

An algorithm is a set of steps of operations to solve a problem performing calculation, data processing, and automated reasoning tasks.
An algorithm is an efficient method that can be expressed within finite amount of Time and space.
The important aspects of algorithm design include creating an efficient algorithm to solve a problem in an efficient way using minimum time and space.
To solve a problem, different approaches can be followed. Some of them can be efficient with respect to time consumption, whereas other approaches may be memory efficient. To Evaluate An Algorithm we have to Satisfy the following Criteria:
INPUT: The Algorithm should be given zero or more input.
OUTPUT: At least one quantity is produced. For each input the algorithm produced value from specific task.
DEFINITENESS: Each instruction is clear and unambiguous.
FINITENESS: If we trace out the instructions of an algorithm, then for all cases, the algorithm terminates after a finite number of steps.
EFFECTIVENESS: Every instruction must very basic so that it can be carried out, in principle, by a person using only pencil & paper.Algorithm : Systematic logical approach which is a well-defined, step-by-step procedure that allows a computer to solve a problem.
Pseudocode : It is a simpler version of a programming code in plain English which uses short phrases to write code for a program before it is implemented in a specific programming language.
Program : It is exact code written for problem following all the rules of the programming language.Algorithm can be described (Represent) in four ways.
Natural language like English:
When this way is chooses, care should be taken, we
should ensure that each & every statement is definite.
(no ambiguity)
2. Graphic representation called flowchart:
This method will work well when the algorithm is small& simple.
3. Pseudo-code Method:
In this method, we should typically describe algorithms as
program, which resembles language like Pascal & Algol
(Algorithmic Language).

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

WHAT IS AN ALGORITHM?
3. • An algorithm is a set of instructions designed to perform a specific
task.
• An algorithm is a step by step procedure to solve logical and
mathematical problems.
• A recipe is a good example of an algorithm because it says what must be
done, step by step. It takes inputs (ingredients) and produces an output
(the completed dish).

• The diagrammatic representation of an algorithm.
• A diagram that represents a workflow or process.
• A picture of the separate steps of a process in a sequential order.
• Flowcharts use rectangles, ovals, diamonds and potentially numerous
other shapes to define the type of step, along with connecting arrows
to define flow and sequence.
• Flowcharts can be used to
• Demonstrate the way code is organized.
• Visualize the execution of code within a program.
• Show the structure of a website or application.

22. Computer Languages
• The programming language is the medium of communication
between human and computer systems. It is the set of
instructions written in a specific style (coding) to instruct the
computer to perform a specific task.
• Three types of Computer Languages
• The computer language is used to communicate with computers.
• Broadly the computer language can be classified into three
categories
• Low level orAssembly language, machine language, and
high-level language.
23. Computer Languages
Machine language
• Machine language or machine code is the native language directly
understood by the computer's central processing unit or CPU.
• This type of computer language is not easy to understand, as it only uses a
binary system, an element of notations containing only a series of numbers
consisting of one and zero, to produce commands.
24. Computer Languages
Assembly Level or Low-Level Language
• Assembly Level Language is a set of codes that can run directly on the
computer's processor.
• This type of language is most appropriate in writing operating systems
and maintaining desktop applications.
• It allows the programmer to perform several tasks like registry access,
memory management and clock cycle correspondence.
25. Computer Languages
High-level programming languages
• These are the machine-independent programming languages, which
are easy to write, read, edit, and understand.
• Languages like Java, .Net, Python, JavaScript, C++, C, C#, and others
(which are very popular now to develop user-end applications). These
languages come under the category of high-level programming
language.
26. Middle-level programming languages
Middle-level programming languages
• The programming languages which have features of Low Level as
well as High-Level programming languages known as "Middle Level"
programming language.
• C programming languages is the best example of Middle-Level
Programming languages as it has features of low level and high-level
programming languages both.
27. Relationship between HLP and MLP
• The High level program(HLP) is called the Source Program and the
Machine language Program translate(MLP) it into Object Program.
28. Compiler VS Interpreter
• A compiler takes entire program and converts it into object code which is
typically stored in a file. The object code is also refereed as binary code
and can be directly executed by the machine after linking. Examples of
compiled programming languages are C and C++.
• Interpreters convert code into machine code when the program is run.
Execute code line by line.
• An Interpreter directly executes instructions written in a programming or
scripting language without previously converting them to an object code
or machine code. Examples of interpreted languages are Perl, Python and
Matlab.
29. BASIS FOR COMPARISON COMPILER INTERPRETER
Input It takes an entire program at a time. It takes a single line of code or instruction
at a time.
Output It generates intermediate object code. It does not produce any intermediate object
code.
Working mechanism The compilation is done before execution. Compilation and execution take place
simultaneously.
Speed Comparatively faster Slower
Memory Memory requirement is more due to the
creation of object code.
It requires less memory as it does not
create intermediate object code.
Errors Display all errors after compilation, all at
the same time.
Displays error of each line one by one.
Error detection Difficult Easier comparatively
Pertaining Programming languages C, C++, C#, Scala, typescript uses
compiler.
PHP, Perl, Python, Ruby uses an
interpreter.
