The code takes an integer input from the user and reverses it using a while loop.

First, it declares two variables - n and sum.

Then, it takes an integer input from the user and stores it in n using the scanf function.

Next, it enters a while loop which continues as long as n is not equal to 0.

Inside the loop, it multiplies sum by 10 and adds the remainder when n is divided by 10. This effectively shifts the digits of sum one place to the left and adds the last digit of n to the ones place of sum.

Then, it divides n by 10 to remove the last digit.

Finally, it prints the reversed integer by using the printf function to output the value of sum.

Note that there is a mistake in the code - the line n/10 should be sum/10 to update the value of sum. Therefore, the corrected code should be:

#include<stdio.h> int main() { int n,sum=0; scanf("%d",&n); while(n!=0) { sum=sum*10+n%10; n/=10; // corrected line } printf("%d",sum);
