Explanation of Solution
Program:
The following program is used to sum the input digits using “do-while” condition:
//include the header file
#include <stdio.h>
//definition of main method
int main (void)
{
//declare the variables
int number, right_digit, s = 0;
//get the input from the user
printf("Enter your number.\n");
scanf("%i", &number);
//check the condition
do
{
//calculate the "right_digit"
right_digit = number % 10;
//calculate the "number"
number = number / 10;
//calculate the sum
s += right_digit;
}
while (number > 0);
//display newline
printf("The sum of the digit is: %i\n", s);
//return statement
return 0;
}
Explanation:
In the above program, declare the required header file. Inside the main method, declare the necessary variables. Get the number from the user and the “do-while” condition is used to add the input digits and finally display the result on the output screen.
Enter your number.
