只有负数正确相加

Question

So I'm trying to write a program that will read in ten whole numbers and outputs the sum of all numbers greater than zero, the sum of all numbers less than zero, and the sum of all numbers, whether positive, negative, or zero. Currently only the total sum and negative sum is adding correctly. My positive sum is always 1 or 0. Any tips to get me in the right direction would help.

Current Code:

#include <iostream>
using namespace std;

int main()
{
int N = 0;
int sum = 0;
int positiveSum = 0;
int negativeSum = 0;

cout << "Number 1" << endl;
cin >> N;
cout << "Number 2" << endl;
cin >> N;
cout << "Number 3" << endl;
cin >> N;
cout << "Number 4" << endl;
cin >> N;
cout << "Number 5" << endl;
cin >> N;
cout << "Number 6" << endl;
cin >> N;
cout << "Number 7" << endl;
cin >> N;
cout << "Number 8" << endl;
cin >> N;
cout << "Number 9" << endl;
cin >> N;
cout << "Number 10" << endl;
cin >> N;

for(int i=0;i<10;i++)
 {
    if (N >= 0 )
    {
      positiveSum += N;
    }
    else
    {
        negativeSum += N;
    }
 }
    sum = positiveSum + negativeSum;
       cout << "The positive sum is= " << positiveSum << endl;
       cout << "the negative sum is= " << negativeSum << endl;
       cout << "The total sum is= " << sum << endl;

return 0;

}

Answer 1

After entering all N s and when entring to the loop, you have only the last N . because after assigning the first number to N you don't process the value but you assigning the next value to N again after asking the user to enter it and so on. Use something like the following

#include <iostream>

int main()
{
    int N = 0;
    int sum = 0;
    int positiveSum = 0;
    int negativeSum = 0;
    
    for(int i=0;i<10;i++)
    {
        std::cout << "Number "<<i + 1<< std::endl;
        std::cin >> N;
        
        if (N >= 0 )
        {
            positiveSum += N;
        }
        else
        {
            negativeSum += N;
        }
    }
    sum = positiveSum + negativeSum;
    std::cout << "The positive sum is= " << positiveSum << std::endl;
    std::cout << "the negative sum is= " << negativeSum << std::endl;
    std::cout << "The total sum is= " << sum << std::endl;

    return 0;

}

And see Why is "using namespace std;" considered bad practice?
