- A switch, case, select or inspect statement is a type of selection control
mechanism that exists in most imperative programming languages such
as Pascal, Ada, C/C++, C#, Java, and so on. It is also included in several other
types of languages. Its purpose is to allow the value of a variable or expression to
control the flow of program execution via a multiway branch (or "goto", one of
several labels).

The Main Reason using switch case :
- To improve clarity, by reducing otherwise repetitive coding, and (if the
heuristics permit) also offering the potential for faster execution through
easier compiler optimization in many cases.

1. The If – else Statement

-The if statement allows the programmer to make
decisions within a program.
- The general format of an if statement is:
If (expression)
statement
-Where expression represents a relational, equality, or
logical expression ( conditional expression) .

If statement (two alternatives)

Form:
If (condition) Note: if condition evaluates to true, then statement is
statement; executed and statement is skipped; otherwise, statement is
else skipped and statement is executed
statement;

If statement (One-Alternatives)
Form:
If (condition) Note: if condition evaluates to true, then statement is
statement; executed and statement is skipped

Format of the if statement
- All if statement examples in this text indent statements. The word else
Is typed without indention on a separate line. The format of the if statement
makes its meaning apparent and is used solely to improve program readability;
The format makes no difference to the computer


 If we know how to write a C expression that is
equivalent of a question such as “Is resting the value of
expression to select a course of action. In C, the
statement is the primary selection control structure

 Me: it’s hard to write c expression. So, I just copy and
paste it into internet.

 A programming language is an artificial language
designed to communicate instructions to a machine,
particularly a computer. Programming languages can be
used to create programs that control the behavior of a
machine and/or to express algorithms precisely.


 1. Open Dev C++
 2. Click File and choose New
 3. Post your Statements
 4. after you post your statement
 5. Save it .choose file and save or
 6. click f9 or you can see it shaped like a square

The above program uses a switch statement to validate and select upon the
users input choice, simulating a simple menu of choices.


When it compiles and run, this will be it look .
The C expression that was type it on be it C++ .
When it compiles and run, this will Dev look
The words are “enter in two number  24”C++
The C expression that was type it on Dev
The words are “enter in two number  24”

Example of Switch
Case Statement , you
Will see the statement
on the link that you see
in this slide.


After I compile it and run it, the statement is now like this. As you
Can see after you answer the 1st question the next question appear
And after you finish all the question the box will disappear. It means finish.

Looping Statements
- Loops execute a block of code a specified number
of times, or while a specified condition is true.
- in PHP, the following looping statements are used:

*The while Loop
* The Do… While Loop
* The For Loop
*The Foreach Loop
*Break and continue statement
http://www.slideshare.net/ilakkiya/looping-statement

While structure is another type of loop statements,
where the condition is checked at first, the iteration
will not stop even if the value changes while executing
statements.

Form:
While(condition)
{
code to be executed;
}


Do while statement is same as the while statement ,
the only difference is that it evaluates the
expression at the end.
Form:
do
{
code to be executed;
}
while (condition):



The for loop is used when you know in advance how many
times the script should run.
Be for statement takes three expressions inside its
parentheses seperated by semi-colons. When the for loop
executes, the following occurs:
The initializing expression is executed. This expression usually
initializes oneor more loop counter, but the syntax allow
expression any degree of complexity.
The condition expression is evaluated. Of the value of
condition is true, the loop statements execute. If the value
of condition is false, the for loop terminates.



Form:

for {initialization; condition:
increment )
{
code to be executed
}



For Each structure is a loop structure used for arrays

Form:
foreach(array as value)
{
code to be executed
}

Foreach (array as key => value)
{
code to be executed
}

Break ends the execution of the for, for each,
while, do-while or switch statement.

Form:
* Break ( optional numeric argument)



“Continue” is used to skip the current loop iteration and
continue with the next iteration of the loop. But “Break” is
to exit from the whole loop.

Form:
* Break ( optional numeric argument)
