How do you find the sum of a 3 digit number in C?

Sum of digits algorithm

1. Step 1: Get number by user.
2. Step 2: Get the modulus/remainder of the number.
3. Step 3: sum the remainder of the number.
4. Step 4: Divide the number by 10.
5. Step 5: Repeat the step 2 while number is greater than 0.

What is reverse number in C?

Reversing number in C means printing the given number back to the front. For example, the given number is 123, then the reverse of this number is 321. Let us see how we can build this logic in the C program.

How do you reverse a set of numbers in C?

6. scanf(“\%d”, &n);
7. while(n!=0)
8. {

What is sum in C program?

printf(“Enter two integers: “); scanf(“\%d \%d”, &number1, &number2); Then, these two numbers are added using the + operator, and the result is stored in the sum variable. sum = number1 + number2; Add Two Numbers. Finally, the printf() function is used to display the sum of numbers.

How do you convert last digit of a number to zero?

Print corresponding word for each case. Remove last digit from num by dividing it by 10 i.e. num = num / 10. Repeat step 2 to 4 till number becomes 0.

How do you get the last digit of a number?

Input number from user. Store it in some variable say num. Extract last digit of given number by performing modulo division by 10. Store the result in a variable say digit = num \% 10. Switch the value of digit found above. Since there are 10 possible values of digit i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 hence, write 10 cases.
