Sum Of First and Last Digit In C++

This is a random c++ code to find the sum of first and last digit of a given number. This code works even if the first digit is Zero '0'.

eg: if the input number is 1234 then the sum of the first digit ie. 1 and last digit ie. 4 will be equal to 5. Which is very easy to find using the while(){} and the % operator.

But if the number is 01234 then the interpreter expluces the preceding 0 if the input is taken as int then the ans will be 5 again but the ans is should be 4 because the first digit is 0 and the last digit is 4 and the addition is 4.

The above problem is tacked with taking the input as string and running throug a simple if-else statement and converting the string input to int using the stoi() funnction.
