Sum of First and Last Digits of a Four-Digit number.
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.) */ #include <stdio.h> main () { int number , last_digit , first_digit , total ; printf ( " Enter the number which is to be operated on: " ); scanf ( "%d" , & number ); last_digit = number % 10 ; total = last_digit ; first_digit = ( number / 1000 ) % 10 ; total = total + first_digit ; printf ( "The total of the first and the last digit of the entered number is: %d" , total ); } /*This program is based on the "Sum of Digits" Program */ The File can be found out at: Download File
