Below is the c++ program which takes an integer x and displays the output as mentioned above - (after the code, attached the sample output images of random input tests) -

#include <iostream>
using namespace std;
int main() 
{
   int x;
   cout<<"Enter x: ";
   cin>>x;
   cout<<endl;
   for(int i=0;i<=x;i++)
   {
       cout<<i<<"        "<<i*i<<endl;
   }
   
   return 0;
}
