C Program to Reverse a Number and Preserve Trailing Zeros

🔁 C Program to Reverse a Number and Preserve Trailing Zeros

#include<stdio.h>
int main( )
{
    int num,reverse=0,original,zero=0,remainder;
    printf("Enter the number:\n");
    scanf("%d",&num);
    original=num;
    while(original%10==0&&original!=0)
    {
        zero++;
        original=original/10;
    }
    while(num!=0)
    {
        remainder=num%10;
        reverse=reverse*10+remainder;
        num=num/10;
    }
    printf("Reversed Number is:%d",reverse);
    for(int i=0;i<zero;i++)
    {
        printf("0");
    }
    printf("\n");
}
  

📝 Explanation:

This program reverses a number while preserving its trailing zeros. For example, 54000 becomes 45 followed by three zeros → Reversed Number is: 45 000.

💡 Sample Output:

Enter the number:
54000
Reversed Number is:45 000
