How can I remove last comma form the loop

Question

int main()
{
    int  num[10];
    
    cout << "Enter 10  numbers\n";
    
    for (int i=0; i < 10; i++) {
        cin >> num[i];
        
    }
    cout << "The even numbers are:";
    for (int i=0; i < 10; i++){
        if( num [i]%2==0){
            cout << num[i] << ",";
        }
        
      
    }
        cout << endl;
        
        cout << "The odd numbers are:";
    for (int i = 0; i < 10; i++){
        if(num[i]%2==1){
            cout << num[i] << ",";
        }
    }
}

I want my output is like this: 2, 4, 6, 7, 8
but the output my program print is: 2, 4, 6, 8,
it has last comma how can I remove it?

You either use just space to separate and put a space before every item. Or, you print a comma before every item, but you only do it after the first (0th) item:

#include <iostream>

int main()
{
    const int count = 5;
    int numbers[count] = { 1, 2, 3, 4, 5 };

    // List just with space separator
    std::cout << "The numebers are:";
    for (int i = 0; i < count; i++)
        std::cout << " " << numbers[i];
    std::cout << std::endl;

    // List with come separator
    std::cout << "The numebers are: ";
    for (int i = 0; i < count; i++)
    {
        if (i > 0)
            std::cout << ", ";
        std::cout << numbers[i];
    }
    std::cout << std::endl;

    return 0;
}

I hope this helps. :)
