Question

1. Write a function called isEven() that uses the remainder operator(%) to determine whether an integer is even or not.

Answer 1

#include <iostream>

using namespace std;

bool isEven(int a){

  return a%2 == 0? true : false;

}

int main()

{

  int a;

  cout<<"Input an integer...\n";

  cin>>a;

  string str = isEven(a) ? " is even.": " is odd.";

  cout<<a<<str;

  return 0;

}
