Write a program of add two digit in C++

This program extracts and adds the two least significant digits of an integer

Source 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 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

#include <iostream.h> #include <conio.h> using namespace std; // Prototype Declarations int addTwoDigits (int num); int firstDigit (int); int secondDigit (int); int main () { cout << " Enter an integer: "; int number; cin >> number; int sum = addTwoDigits (number); cout << " \n Sum of last two digits is: "<< sum ; getch(); return 0; } // main /* ============== addTwoDigits =================== Adds the first two digits of an integer. Pre num contains an integer Post return sum of two least significant digits */ int addTwoDigits (int number) { int result = firstDigit (number) + secondDigit (number); return result; } //add two digit /* ============== firstDigits =================== Extracts the least significant digits of an integer. Pre num contains an integer Post Return least significant digits */ int firstDigit (int num) { return (num % 10); } /* ============== secondDigits =================== Extracts second least significant digits of an integer. Pre num contains an integer Post Return digit is 10s position */ int secondDigit (int num) { int result = (num / 10) % 10; return result; getch (); return result; } //secondDigits

Result:

 Enter an integer:  23

 Sum of last two digits is:   5
