from 1 to x.

Answer 1

SOLUTION CODE

#include <iostream>
using namespace std;


int main()
{
  cout<<"Enter an integer to get the perfect numbers upto that point: ";
  int my_integer;
  cin>>my_integer;
  //Now let the get the perfect numbers
  cout<<"The following are perfect numbers between 1 and "<<my_integer<<endl;
  for(int i = 2; i < my_integer; i++)
  {
  	//declare a variable to store the sum of the integers
  	int sum = 0;
  	for(int j = 1; j<=((i/2)+1); j++)
  	{
  	 if(i%j==0)
	   {
	   	 sum = sum + j;
	   }	
	}
	
	if(sum==i)
	{
		cout<<i<<"  ";
	}
  }
    return 0;
}
