Write a C++ program that will check whether the last digit of any integer number is divisible by 3 or not by taking user input.

Code: 

#include <iostream>

using namespace std;

int main(){

    int x;

    cout << "Enter the Number: ";

    cin >> x;

    x %=10;

    if (x%3==0)

        cout << "Divisible";

    else

        cout << "Not Divisible";

}

Output: 

Enter the Number: 21

Not Divisible

Process returned 0 (0x0)   execution time : 4.639 s
