How is compiler and run of Linux c program with example?

Answer 1

You start by writing your c code in a text editor. An example of some c code (syntax not guaranteed to be correct):

#include <stdio.h>

int main ();

{

printf("Hello, World!!\n");

return 0;

}

Then, you save this file, as whatever, for this example as 'Hello.c'.

Then, open a Terminal window (command line) and change your directory to where your Hello.c is saved at, using 'CD <filepath>' (sans brackets). Then, type 'gcc Hello.c -o Hello'. The 'gcc' command compiles your code, and the -o flag changes the output filename to whatever you specify, in this case Hello. Then, to run your new program, type './Hello'. The ./ specifies the current directory.

Congrats, you have written, compiled, and ran your first program in C using a Linux platform.
