Simple technique to understanding all 32 printf functions

main.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char* argv[]) {
    char buf[100];
    va_list args; // needs initialization
    
    printf("Example\n");
    fprintf(stdout, "Example\n");
    sprintf(buf, "Example\n");
    snprintf(buf, 100, "Example\n");
    vfprintf(stdout, "Example\n", args);

    return 0;
}
