Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to check even or odd using functions
#include <iostream>
using namespace std;
int isEven(int num)
{
return !(num & 1);
}
int main(){
int num;
// Inputting number from user
cout<<"Enter any number: ";
cin>>num;
// If isEven() function return 0 then the number is even
if(isEven(num))
{
//printing even number
cout<<"The entered number is even.";
}
else
{
//printing odd number
cout<<"The entered number is odd.";
}
return 0;
}
Result
