Write C++ program to find first and last digit of any number

Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream>
#include <math.h>
 
using namespace std;
 
int main()
{
    int num, last;
 
     //Reading a number from user
    cout<<"Enter any number:";
    cin>>num;
 
    last = num%10;
 
    cout<<"The last digit of entered number: "<< last<<endl;
 
    while(num>=10)
    {
        num = num/10;
    }
 
    cout<<"The first digit of entered number: "<<num;
 
    return 0;
}

Result
