Loop

[needhelpplease]

I have to write a loop code that sorts the inputs from a user from lowest to highest when they enter 2 separate integers. This loops 3 times. Then at the end it is suppose print out the sum of all the integers entered. My code is printing the sum between each request for integers rather than at the end. How can I have it only print at the end.

#include <iostream>
#include <stdio.h>
#include <stdlib.h>

using namespace std;

/**
 * This program uses if statments to sort 2 integers entered in by a user in 
 * numerical order from lowest to highest. Then it will find the sum of all 
 * the integers entered and the average.
 * 
 * @creator 
 */

int main(int, char**) {
   
    for(int i= 0, sum=0; i<3; ++i) {
    int x,y;
    cout<<"Enter 2 integers: ";
    cin>>x>>y;
        if (x>y)
           cout<<x<<" "<<y<<" sorted is "<<y<<" "<<x<<endl ;
             else
                cout<<x<<" "<<y<<" sorted is "<<x<<" "<<y<<endl;
    sum+= x+y;
    cout <<sum<<endl;
}
    
   (void) system("pause");      
   return EXIT_SUCCESS;
}

    int sum = 0;
    for ( int i = 0; i<3; ++i ) {
        // ...
    }

    cout << sum << '\n' ;
    // ...

When I have tried taking the cout for the sum out of the for{ } statement it comes back with an error code saying the sum has changed as well as an obsolete binding error.

[name lookup of `sum' changed for new ISO `for' scoping]
[using obsolete binding at `sum']


This code shows the cout sum outside the for statement but it won't compile because of the above errors. Same kind problem if I pull the sum+= out of the for statement

#include <iostream>
#include <stdio.h>
#include <stdlib.h>

using namespace std;

/**
 * This program uses if statments to sort 2 integers entered in by a user in 
 * numerical order from lowest to highest. Then it will find the sum of all 
 * the integers entered and the average.

int main(int, char**) {
   
    for(int i= 0, sum=0; i<3; ++i) {
    int x,y;
    cout<<"Enter 2 integers: ";
    cin>>x>>y;
        if (x>y)
           cout<<x<<" "<<y<<" sorted is "<<y<<" "<<x<<endl ;
             else
                cout<<x<<" "<<y<<" sorted is "<<x<<" "<<y<<endl;
    sum+= x+y;
}
    
    cout <<sum<<endl;
       
   (void) system("pause");      
   return EXIT_SUCCESS;
} */

As far as I can see, cire answered this correctly, I modified your program let me know if it works

#include <iostream>
using namespace std;

/**
 * This program uses if statements to sort 2 integers entered in by a user in
 * numerical order from lowest to highest. Then it will find the sum of all
 * the integers entered and the average.

int main()
{
    int sum = 0;
    for(int i=0; i<3; ++i)
    {
        cout<<"Enter 2 integers: ";

        int x, y;
        cin >> x >> y;

        if(!cin)
            return 1;

        if (x>y)
            cout<<x<<" "<<y<<" sorted is "<<y<<" "<<x<<endl;
        else
            cout<<x<<" "<<y<<" sorted is "<<x<<" "<<y<<endl;

        sum += x + y;
    }

    cout << "The sum is: " << sum << endl;

    //todo work out average

    cout << "Press any key to continue . . .\n";
    cin.ignore(99999, '\n');
    cin.get();
}
