[C]: printf / scanf functions are evil

I'm just starting to learn C and the first exercise made in class was to make a program that prints the sum of two integers.

This program:

#include <stdio.h>
#include <stdlib.h>
int main (void) {
  int n1,n2;
  printf("1st int: ");
  scanf("%d",&n1);
  printf("2nd int: ");
  scanf("%d",&n2);
  printf("Sum = %d\n",n1+n2);
  return EXIT_SUCCESS;
}

I showed it to some of my older classmates and went batshit insane with it saying: DO NOT USE PRINTF AND SCANF, THEY ARE NOT FUCKING SAME and other stuff.

Will someone please input on this matter?
Thank you!

Im looking for a print function, it cant be printufu (thats japanese for printf) or any stdio function. It has to be of 2 or more parameteru (thats japanese for 2 parameters) and has be be chibi (small) sized. And has to be really kawaii (cute). Also It has to be about 10-20 bux. And you have to post documentation of it first (i want to make shure it's kawaii [cute]). And it would be nice if it came with matching input reading (WITH error handling). OH! and it CANNOT have any complicated syntax, or be made out of C. It has to be made of C++, or something like that. Also it would be nice if it was made in japan. and not in china or corea (korea) or whatever. I have found a function similar to the one im describing in sourceforge, but it was 1 parameteru, and i dont want my formatou (formatting) to touch my other things (it can get mixed up and i would not like that, plus 2 paraneters looks more kawaii)
