Count number of even and odd numbers from input

You have an unneccessary amount of variables. You don't need to have
a variable to hold the remainder for each number.
Just have a function that determines whether the input number is odd
or even. I think you might have to rethink the logic of your
program.




//Your function should do the following:
//MAX is a const int. In your case it is 5
    for(int i=0; i&lt;MAX; i++){
        if(numbers[i] % 2 == 0)
            evenNumbers++;
        else
            oddNumbers++;

        sum += numbers[i];
    }


Here is how I would have done it:

#include &lt;iostream&gt;
#include &lt;vector&gt;
#include &lt;iterator&gt;

using std::cin;
using std::cout;
using std::endl;
using std::vector;



int main(){

    int value = 0;
    int oddNumbers(0), evenNumbers(0), sum(0);


    std::istream_iterator&lt;int&gt; begin(cin);
    std::istream_iterator&lt;int&gt; end;


    //while(cin &gt;&gt; value)
    //  numbers.push_back(value);

    //Instead of a while loop, I use input stream iterators.
    vector&lt;int&gt; numbers;
    std::back_insert_iterator&lt;std::vector&lt;int&gt;&gt; iter (numbers);

    std::copy(begin,end,iter);


    //Range based for-loop (C++11)
    for(auto i : numbers){
        if(i % 2 == 0){
            evenNumbers++;
        }else {
            oddNumbers++;
        }

        sum += i;

    }

    cout &lt;&lt; "# of odd numbers: " &lt;&lt; oddNumbers &lt;&lt; "\n";
    cout &lt;&lt; "# of even numbers: " &lt;&lt; evenNumbers &lt;&lt; "\n";
    cout &lt;&lt; "Sum of all numbers: " &lt;&lt; sum &lt;&lt; endl;



}
