Write a program that Print Least Significant Digit in C++

This program print the first digit of an integer read from the keyboard

Souce Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#include <iostream.h> #include <conio.h> using namespace std; // Prototype Declarations int firstDigit (int num); int main () { cout << " Enter an integer: "; int number; cin >> number; int digit = firstDigit (number); cout << " Least Significant digit is: "<< digit << endl; getch(); return 0; }// main /* ============= firstDigit ================= This function extracts the least significant digit of an integer pre num contains an integer post Returned least significant digit */ int firstDigit (int num) { return (num % 10); } // firstDigit

Output:

 Enter an integer: 345
 Least Significant digit is: 5
