Problem with program output

Hi guys. I am having a problem with a project for my Computer Science class. The basic program works but I am having trouble getting the output the professor asked for. Here is my source code:

Code:

#include<iostream>
#include<iomanip>
using namespace std;

#define clear() cout << (char)(27) << '[' << '?' << '3' << 'l';
#define cur_yx(y,x) cout << (char)(27) << '[' << y << ';' << x << 'H';
main()
{
  int start, end, sum, square, sum_cubes, sum_terms, cubes_terms;
  cout<<"Input Series Start Here: ";
  cin>>start;  
cout<<"Input Series End Here: ";
  cin>>end;
    sum_terms = start, start++;

    cubes_terms = start*start*start;
    cubes_terms++;
  sum = (((0.5)*(end*end)) + (0.5*end));
  square = sum * sum;
  sum_cubes = (end*(end + 1) / 2) * (end*(end + 1) / 2);
  cout<<"Sum = "<<start<<" + "<<sum_terms++<<" = "<<sum<<endl;
  cout<<"Square of Sum = "<<square<<endl<<endl;
  cout<<"Sum of Series Terms Cubes = "<<cubes_terms<<" = "<<sum_cubes<<endl<<en\
dl;

}

As I said, the main program works. It calculates the sum, square and sum of the cubes. However, the professor has asked for a specific output. He wants the output to say the following:

For example, if the two integers were 1 and 3, the output should
be:

Sum = 1+ 2 + 3 = 6
Square of Sum = 36

Square of Cubes = 1 + 8 + 27 = 36

What I am having trouble with is how to get the program to output 1+2+3 or 1+8+27 along with the answer, which in this is 36. Any help would be appreciated. Thanks.

Your program does not work correctly if the start number is not 1.

You are almost certainly going to need a loop to print the output in that format.

Code:

    cout << "Sum: ";
    for(i = start; i <= end; i++) {
        cout << i;
        if(i < end) cout << " + ";
    }
    cout << " = " << sum << endl;

ARRGGHH, my eyes, my eyes! Macros are EVIL!! somewhere between telemarketers and hitler on a scale of 1 to evil.


as spydoor said you'll need a loop to output your values, and probably a loop to calculate them too. what happens if someone inputs 1 and 9999?

Thanks spydoor and chaosengine. I got the desired output. Chaos, the macros were not my idea. The professor instructed us to place that in every program.

Thanks again guys.

I'd look into having him fired.

There's worse things to fire a guy for than macros, Chaos.

Code:

main()

and no

Code:

return x;

for example....

that's pretty bad alright, but those could be the op's fault.

Plus I heard he seduces his students. Just what I heard... s'all I'm sayin'.
