A remarkably simple and highly readable programming language resulted in groundbreaking advancements in the IT industry. 2:48-Importance and unraveling the powerful capabilities of C, The widespread use of C started to take over the IT industry. Unraveling the potential of C, the designers began to discover new possibilities that led them to focus on the big picture. 3:56-C's cutting-edge features The designers at Bell Laboratories ensured that their programming language solved the issues with B and BCPL and the ones they had foreseen. 6:35-The popular real-world applications of C -UNIX operating system -google file system -Mozilla -Graphical user interface 8:30-The advantages and disadvantages of C 10:34-The popular IT companies and their domains that employ C · MasterCard · IBM · Flipkart · Dell · Twitter · GitHub and twitch 11:09-First c program. 🔥 Explore our FREE courses with completion certificates: https://www.simplilearn.com/skillup-f... ✅Subscribe to our Channel to learn more about the top Technologies: https://bit.ly/2VT4WtH ⏩ Check out the C++ Programming training videos: https://www.youtube.com/playlist?list... #IntroductiontoCProgrammingLanguage #CLanguage #CProgramming #CProgram #CProgrammingLanguage #LearnCProgramming #HowToCodeInCForBeginners #CTutorialForBeginners #LearnCProgramming #Simplilearn Dennis Ritchie, a computer scientist, was able to identify the gaps and tap out the best features from both B and BCPL languages to invent a new hybrid.

C++ is an enhanced and extended version of C programming language, developed by Bjarne Stroustrup in 1979 as part of his Ph.D. project. Bjarne developed what he called ‘C with Classes’ (later renamed C++) because he felt limited by the existing programming languages that were not ideal for large scale projects. He used C to build what he wanted because C was already a general-purpose language that was efficient and fast in its operations. ✅C++ Career Prospects: With just C++ programming expertise, you will have excellent job opportunities, salaries, and career prospects. However, for a career based on programming languages such as Java and Python (which are in more demand than C++) or for careers based on front-end, back-end, and full-stack
