C Language Tutorial

C language is a general-purpose, procedural computer programming language. In 1972, Dennis Ritchie developed C language at Bell Labs to port and develop the UNIX operating system.

C language is widely used in computing and is as popular as Java programming language, both of which are extensively used by modern software programmers.

The latest standard for C language is C18, preceded by standards such as C17, C11, and C99.

Compiling/Executing C Programs

Example

#include <stdio.h>

int main()
{
    /* My first C program */
    printf("Hello, World! \n");

    return 0;
}

Example Analysis:

All C language programs require the main() function. Execution starts from the main() function.
/* ... */ is used for comments.
printf() is used for formatted output to the screen. The printf() function is declared in the "stdio.h" header file.
stdio.h is a header file (standard input output header file), and #include is a preprocessor command to include the header file. If the compiler encounters printf() without finding the stdio.h header file, a compilation error will occur.
return 0; statement is used to exit the program.
