C Program to Sum of First and Last Digits of a Four-Digit number

C Program to Sum of First and Last Digits of a Four-Digit number

How to write a C Program to Sum of First and Last Digits of a Four-Digit number in C Programming Language ?


Solution:

This program is based on the "sum of digits" program discussed previously.
This program also has some usage of the Modulus Operator.

If a four-digit number is input through the keyboard,
write a program to obtain the sum of the first and the last digit of this number.
/*HINT: If a number is divided using % , then the number to the right side of the decimal point is the result. (This applies only to integers.) */
