18. 2.24 (Odd or Even) Write a program that reads an integer and determines and prints whether it’s odd or even. [Hint: Use the remainder operator (%). An even number is a multiple of two. Any multiple of 2 leaves a remainder of zero when divided by 2.]
#include <iostream>
using namespace std;
int main()
{
int num;
cout << "Enter a number: ";
cin >> num;
if ( num % 2 == 0 )
cout << "The number " << num << " is even." << endl;
if ( num % 2 != 0 )
cout << "The number " << num << " is odd." << endl;
return 0;
}
