The C compiler is a software application that transforms the human-readable C program code to machine-readable code. The process of transforming the code from High-Level Language to Machine Level Language is called "Compilation". The human-readable code is the C program that consists of digits letters, special symbols, etc. which is understood by human beings. On the other hand, machine language is dependent on the processor and processor understands zeroes and ones (binary) only. All C program execution is based on a processor which is available in the CPU; that is why entire C source code needs to be converted to the binary system by the compiler.
This tutorial is written for Windows, Unix / Linux, and MAC users. All code has been tested, and it works correctly on all three operating systems.
Since there are various compilers available into the online market, here are the lists of some of the frequently used ones:
All of these above compilers for C are free to download, but there are some other paid C compilers also available, or programmers can get it for trial version:
