Write a C program to split a number and then add all factorial digit.

Split a number and then add all factorial digit

3. Take 3 digit number from user. Split the digits of the number using a user defined function splitter(). Find the factorial of each digit using a user defined function find_factorial(). Finally, print the sum of the factorials using anther user defined function calculate_sum().

Sample Output

Input Number: 123
Output : 9

        number = number/10;
        digit++;

int main()
{
    int number, digit;
 
    printf("Input Number: ");
    scanf("%d", &number);
 
    digit = splitter(number);
 
    for(int i = 0; i < digit; i++)
    {
        find_factorial(arr[i]);
    }
 
    printf("Output : %d\n\n", factorialSum);
    return 0;
