What is C programming language?
C is the powerful general purpose computer programming language that support structured programming that means you can use C to create lists of instructions for a computer to follow. C is the fast, portable and available in all platforms.
C language was developed at Bell Labs by Dennis Ritchie for the UNIX operating system in the 1970.
If you are new to programming language than C is the very good choice to start your programming journey.
C is also called compiled language because once you write your C program, you must run it through with the help up of C compiler to turn your program into an executable that the computer can run (execute).
The C program is the human-readable kind, while the executable that comes out of the compiler is the machine-readable and executable form. What this means is that to write and run a C program, you must have access to a C compiler.
Why learn C?
- The advantage to knowing C language is that you have a very good knowledge of how a computer works.
- Opportunity to work on open source projects that impact millions of people.
- You will find that it is very easy to learn.
- All C program starts with the main() function and it is mandatory.
- You may use the required header file that’s necessary in the program.
- C is the case-sensitive so the use of uppercase letter and lowercase letter have different meanings.
- The C program ends when the program encounters the return statement inside the main() function. However, return statement inside the main function is not necessary.
- The statement in the C programming ends with the semicolon.
