Basic structure of C

Let's start C

#include <stdio.h>  (it means preprocessing command) It generally tells to the compiler that we need a (#include <stdio.h>)  named file in this program, then this program will work.

int main() (it is a function) We have used functions to break a programs in a parts, main is a very special kind of function because it is a initial point of a program, Where as the int means the integer value returns to the operators.

return 0;  It will return the integer to the operating system, where as (0) means it will return 0 if everything will be fine (in true condition).

move on to code:👇

#include <stdio.h>

int main()

{

    printf("Hello world\n");

    return 0;

}
