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 (){intnumber, 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 */
