Step 1 of 5

Your first program

Every C program starts running at a function called main. Inside it, printf prints text to the screen.

#include <stdio.h>

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

#include <stdio.h> pulls in the standard input/output library, which is where printf lives.
\n is a newline: it ends the line.
return 0; tells the operating system the program finished successfully.

Your turn: fill in the blank so the program prints Hello, World!.
