Overview of C Programming Language
C is a programming language developed by Dennis Ritchie at AT&T Bell Laboratory in 1972. There are some aspects of any programming language, they are
- The way it stores the data and how we operate on the data.
- How do we read input output
- The control sequence, the flow of execution
Why start with C?
- C programming gives head start to the programmers. It makes easy to learn other programming languages like C++, Java, as their syntax is majorly in line with C.
- Most parts of the operating systems like windows, Linux and Android are written in C.
- C is used in many embedded systems.
- C programming is used in game development.
- C is faster than python, java.
- C programming is widely used language and is consistently in the top positions of the TIOBE index.
- C programming language is well suited for structured programming.
In the next section we will begin with the C programming basics.
