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; }
