The addition problem

[CyBerFirEZ]

Hi, I have really searched my brain for a solution but i cant seem to find one, and I really need some code to help me.

I can do something like:
a + b = r;
cout << r;

but that is easy. What I want is that when the user goes onto an addition function, they can type the integers separated by commas ie.

1,3,6,23,2

and this would do 1+3+6+23+2, and display the output. The user should be allowed to enter as many numbers as they want.

How do I do this?

Any help would be appreciated.

Thnx :-)

Won't work, the association is on the wrong side.

How would you go about starting this? I'm going to push you here because you tend to ask for code. How would you start to develop an algorithm for this?

Hint: if you put the input in a loop, you could have an extra variable that did nothing but count...

This is my code for my math console application so far:

 // math.cpp : main project file.
 
#include "stdafx.h"
 
#include <iostream>
 
#include <string>
 
#include <sstream>
 
using namespace std;
 
 
int main()
{
 
   /* ... snipped a==1 and a==2 ... */
 
 if ( a == 3)
    {
     string b;
     int c;
     cout << "Parameter 3 has been called. This is the addition function. \n";
     cout << "USAGE: no1 + no2 + no3 + no4+...... | A default error will result in TOTAL to equal 0. Leave spaces between addition symbol and integers. \n";
     getline (cin, b);
     stringstream(b) >> c;
     cout << "TOTAL:" << c << endl;
    }
 
    } while (a != 1);
    return 0;
}
 

Can anyone see any problems with it?

Please read the Posting Guidelines thoroughly.

They ask that you use code tags, ask specific questions (and not "what is wrong with this"), etc... Please follow the rules of the site.

Have you run your code through a compiler? I would imagine that would tell you if anything is wrong with it very quickly.

[CyBerFirEZ]

Well, ok sorry about that.
My compiler sees no errors (ENU Visual Studio C++ express 2005).
But when I use option 3, it nevers waits for user input on the getline bit (around line 54), and says TOTAL: 1202464

Everything else works fine, so where am I going wrong with option 3?

[TRScheel]

I feel that your answer will lie in what the value of b is after the getline call.

[CyBerFirEZ]

and the answer is?
?????

[CyBerFirEZ]

now total is 1241320

[TRScheel]

now total is 1241320

My guess is that b is a memory address, not a value

[CyBerFirEZ]

so how to I fix it, how do I modify my code dude?
