Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to find the sum of first and last digit of any number
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int num, sum=0, firstDigit, lastDigit;
//Reading a number from user
cout<<"Enter any number:";
cin>>num;
lastDigit = num % 10;
firstDigit = num;
while(num >= 10)
{
num = num / 10;
}
firstDigit = num;
//Finding sum of first and last digit
sum = firstDigit + lastDigit;
cout<<"Sum of first and last digit: "<<sum;
return 0;
}
Result
