Print Hello World

Use the GCC compiler to compile the source code and print the HelloWorld string in the terminal.

1. Create new folders and files

mkdir Demo
cd Demo/
nano HelloWorld.c

2. Write source code

Add the following code to the newly created HelloWorld.c file:

​x
// This is the first program

#include <stdio.h>

int main(void)
{
printf("Hello World!\n");
    
return 0;
}

Hold down Ctrl+X, enter Y, then press Enter to save and exit!

3. Compile source code

Compile HelloWorld.c using GCC and name the resulting executable HelloWorld:

xxxxxxxxxx
gcc HelloWorld.c -o HelloWorld

4. Run the executable file

xxxxxxxxxx
./HelloWorld

The above are the steps to write, compile source code and generate executable files!
