I tried to run centip3de's code yesterday evening, and endet up doing a few changes. Not that is wassent fine.
But now that you got the code in your editor, it's hard not to start addding a little here and there.

Code: Select all

#include <iostream>
#include <sstream>

int main()
{
    int iCount = 0, iResult = 0;
    std::string sInput;
    while(iCount < 20)
    {
        int iNumIn;
        while (true)
        {   
            std::cout << "Enter a number: ";
           
            std::getline(std::cin, sInput);
           
            std::stringstream sStream(sInput);
            if (sStream >> iNumIn)
                 break;
            std::cout << "I dont think that was a number. \n";
        }
        bool isPositive = iNumIn > 0;

        if(isPositive)
        {
            iResult += iNumIn;
        }
        iCount++;
    }
    std::cout << "And the final calculation is... " << iResult << "!";
    std::cin.get();
    return 0;
}

I changed the endl to a \n. I remember learning that it is bad practice flushing if there is no reason for it. I havent used c/c++ for a long time, but i found this: http://stackoverflow.com/questions/5492 ... 05#5492605

Sorry, double post.

Hey guys I am really thankful for the info but I am not trying to start arguments on here. So I have been looking and I have gotten the code below but its not just giving me the sum correctly. also if you input a neg number is in the beginning it doesnt sum. Any suggestions?

#include<iostream>
using namespace std;

int main()
{
cout << "Enter a series 20 of numbers with a space between numbers ";
int number;
int sum = 0;
for(;;)
{
cin >> number;

if( number <= 0)
{
cout << sum << endl;

}
sum += number;
}
system("PAUSE");
return 0;
}

There you go. Made a few simple changes, you should be able to see the diffrence.

Code: Select all

#include<iostream>
using namespace std;

int main()
{
cout << "Enter a series 20 of numbers with a space between numbers ";
int number;
int sum = 0;
for(int iCount = 0;iCount < 20; iCount++)
{
     cin >> number;

     if(!(number <= 0))
     {
      sum += number;
      //cout << sum << endl;
     }
}
cout << "sum = " << sum; 
cin.ignore();
cin.get(); //system("PAUSE");
return 0;
}

shdwcat- It wasn't an argument, it's just how HTS criticizes code.

Thx Acidiferous that is what I needed. Thx all for the help.

yes... yes...
we shall use this 'argument' to spread our influence over the weak. and when the time comes, THE GEEKS SHALL INHERIT THE EARTH!!11!!11!!11

That depends. If the "weak" are criticism-resilient, you're going to have a bad time.

I know it's hella late but I was bored plus it's been a while since I used c++ so here's my take on it:

Code: Select all


#include <iostream>

int main()
{
    int number, iterator, total = 0;

    for(iterator = 0; iterator < 20; ++iterator)
    {
        std::cout << "Enter a number: ";
        std::cin >> number;

        if(number > 0)
            total += number;

        number = 0;

    }

    std::cout << "Total = " << total << "\n";


    return 0;

}

there's a reason they're called the 'weak'.
