Sum The Digits Of A Number C Programming Example Youtube Prime numbers are numbers that have only 2 factors, 1 and themselves. for example, 2, 3, 5, 7, 11, etc are some of the first prime numbers. here we will see whether a number can be expressed as the sum of two prime numbers using a c program. example input: 7output: yesexplanation: 7 can be expressed as sum of 2 and 5 which are prime input: 11output. To get last digit modulo division the number by 10 i.e. lastdigit = num % 10. add last digit found above to sum i.e. sum = sum lastdigit. remove last digit from number by dividing the number by 10 i.e. num = num 10. repeat step 2 4 till number becomes 0. finally you will be left with the sum of digits in sum.
Sum Of Digits In A Given Number C Programming By Snehatech Youtube For example, number 125 contains three individual digits, i.e., 1, 2, and 5. to find the sum of individual digits of a number (input), we need to get and add them. in your school, you must have learned how to divide two numbers. we divide a number by 10 (divisor), find the remainder, and store it. Next, condition in the while loop will make sure that the given number is greater than 0 (means positive integer and greater than 0) for the c program to find sum of digits demonstration, user entered value: number = 4567 and sum= 0. reminder= 456 % 10 = 6. sum= 7 6 => 13. number= 456 10 => 45. Follow the below steps to solve the problem: get the number. declare a variable to store the sum and set it to 0. repeat the next two steps till the number is not 0. get the rightmost digit of the number with help of the remainder ‘%’ operator by dividing it by 10 and adding it to the sum. divide the number by 10 with help of. Last updated on september 23, 2020. the following c program finds the sum of digits of a number. expected output: run 1: run 2: try it now. how it works. the following table demonstrates the algorithm we used to find the sum of digits of the a given number: recommended reading: c program to find the factorial of a nu….
