Results of executing a Hello World program in a console (apparently on a Linux or Unix system).
A Hello World program, as first introduced in the book The C Programming Language, is a very short program that typically just prints a word or two of output to a console. Such a program is often one of the first programs that a programmer writes when learning a programming language, as it provide's a cursory introduction to the language's syntax and output.
Example in C
#include <stdio.h>
int main()
{
printf("This is my first C program!\n");
return 0;
}
