Question

5. Count the Trail

by CodeChum Admin

Help, I'm lost!

I usually find my way around here but I somehow lost my glasses along the way. I can easily get back home as long as I can tell how many zeroes I left in my trail. Would you mind telling me how many zeroes are trailing?

Note: Trailing zeroes are the zeroes found at the right side of a number.

Input

1. The number to be evaluated

Constraints

This can only be a positive integer.

Output

The first line will contain a message prompt to input the number to be evaluated.

The second line will contain the number of trailing zeroes.

Answer 1

#include<stdio.h>

 

int main()

{

      int num, temp, count = 0;

      printf("\nEnter a Number:\t");

      scanf("%d", &num);

      temp = num;

      while(num >= 0)

      {

            if(num%10 == 0)

            {

                  count++;

                  num = num / 10;

            }

            else

            { 

                  break;

            }
      }       

      printf("\nNumber of Trailing Zeros in %d = %d\n", temp, count);

      return 0;

}
Enter a number: 2000
Number of Trailing Zeros in 2000 = 3
