Question

Write a complete C++ program asking the user to enter numbers one by one. User enters only whole numbers 0 and 10. Once the user enters 0, then the program should print sum of only odd numbers entered by user prior to 0. A valid scenario given below:

Enter a number: 5

Enter a number: 3

Enter a number: 2

Enter a number: 3

Enter a number: 8

Enter a number: 0

Sum of the odd numbers you entered is 11.

Answer 1

// C++ program to asking the user to enter numbers one by one and calculating the sum of all odd numbers entered by the user

#include <iostream>

using namespace std;

int main()

{

       int sumOdd = 0;

       int num;

       // input of number

       cout<<"Enter a number : ";

       cin>>num;

       // loop that continues till user enters 0

       while(num != 0)

       {

             // check if num is odd, add num to sumOdd

             if(num%2 != 0)

                    sumOdd += num;

             // input of number

             cout<<"Enter a number : ";

             cin>>num;

       }

       // display the sum of all odd numbers entered by the user

       cout<<"Sum of the odd numbers you entered is "<<sumOdd<<endl;

        return 0;

}

//end of program

Output:
