[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!

This version of C:\Users\haskal\Documents\Downloads\qbasic\qbasic.exe is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

Windows doesn't even know what architecture it's running on!

Even stranger is that it should run fine on a 32-bit Windows¹, so it has to be x64.

_{¹ As far as I know.}

The "shit" version of Windows 7 breaks support for DOS apps.
