Hello C

Start with a tiny C program that stores a name and prints a greeting.

hello.c

#include <stdio.h>

int main(void) {
    const char *name = ;
    printf("Hello, %s!\n", name);
    return 0;
}

#include <stdio.h>

int main(void) {
    const char *name = ;
    printf("Hello, %s!\n", name);
    return 0;
}

#include <stdio.h>

int main(void) {
    const char *name = ;
    printf("Hello, %s!\n", name);
    return 0;
}

main `main` is the function where a C program starts running.

printf `printf` writes formatted text to standard output.
