Question

Write a C++ program to read a positive integer greater than 0, the program should compute and display the following:

- Sum of odd digits in the number

- Count of even digits in the number

- The smallest digit.                   

For example, if the input is 24536, then

Sum of odd digits in the number = 8

Count of even digits in the number = 3

Smallest digit = 2

Answer 1

#include <iostream>

using namespace std;

int main() {
    int n, evens = 0, odds = 0, smallest = 9, d;
    cout << "Enter a positive integer: ";
    cin >> n;
    while (n > 0) {
        d = n % 10;
        n /= 10;
        if (d < smallest)
            smallest = d;
        if (d % 2 == 0)
            evens++;
        else
            odds += d;
    }
    cout << "Sum of odd digits in the number = " << odds << endl;
    cout << "Count of even digits in the number = " << evens << endl;
    cout << "Smallest digit = " << smallest << endl;
    return 0;
