Write a program that computes the difference between non-negative integers. Input Each line of the input consists of a pair of integers. Each integer is between 00 and 1015 (inclusive). The input is terminated by end of file. Output For each pair of integers in the input, output one line, containing the absolute value of their difference.

Explanation:

Here is my solution:

#include <iostream>

#include <cmath>  

using namespace std;

int main(){

   int x;

   int y;

   int z;

   cin >> x >> y;

   if(x && y <= 1000000000000000){

       z=x-y;

       cout << std::abs (z);

   }

}

But the problem is my answer is wrong, please help me correct my answer and explain why it was wrong.

the only way i would see could be an autoclicker type software. but that is very time consuming.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
