C Program Sum of digits of a Five Digit Number

C Program Sum of digits of a Five Digit Number.If a five-digit number is input through the keyboard, write a c program to
calculate the sum of its digits.

void main ()
{
int number, last_digit, next_digit, total;
printf ("Enter the number whose sum of digits is to be calculated: ");
scanf ("%d", &number); 
last_digit = number%10;
total = last_digit; 
next_digit = (number/10) % 10; 
total = total + next_digit; 
next_digit = (number/100) % 10; 
total = total + next_digit;
next_digit = (number/1000) %10; 
total = total + next_digit; 
next_digit = (number/10000) %10; 
total = total + next_digit; 
printf ("The sum of the digits of the entered number is: %d", total); 
}

Logic :  Use the Modulus Operator '%"  Using  the normal division operator  " / " returns the quotient.
Using "% " the modulus Operator returns the Remainder.

Fibonacci Sequence using Recursion.

Write a recursive function to obtain the first 25 numbers of a Fibonacci
sequence. In a Fibonacci sequence the sum of two successive terms gives the
third term. Following are the first few terms of the Fibonacci sequence:
1 1 2 3 5 8 13 21 34 55 89 ...


#include
main()
{

static int prev_number=0, number=1; // static: so value is not lost

int fibonacci (int prev_number, int number);

printf ("Following are the first 25 Numbers of the Fibonacci Series:\n");

printf ("1 "); //to avoid complexity

fibonacci (prev_number,number);


}

fibonacci (int prev_number, int number)

{
static int i=1; //i is not 0, cuz 1 is already counted in main.
