Question

Write the function prototype and the definition of a function call "oddoreven" that determine if an integer value is ODD or EVEN. The function will return a string containing that message. Use only ONE function! As an example if an integer value of 20 was passed to that function then the function will return "20 is an Even Number." if an integer value of 35 was passed to that function then the function will return "35 is an Odd Number."

Answer 1

#include <iostream>
#include <string>
using namespace std;

string oddoreven(int number);

int main() {
    int number;
    cout << "Enter a number: ";
    cin >> number;
    cout << oddoreven(number) << endl;
    return 0;
}

string oddoreven(int number) {
    string result = std::to_string(number);
    if (number % 2 == 0) {
        result += " is an Even Number.";
    } else {
        result += " is an Odd Number.";
    }
    return result;
}
