Write a program that prompts the user to enter a four-digit integer and displays the number in reverse order. here is a sample run:
enter an integer: 5213
3
1
2
5

Following are the code that is written in c language

#include <stdio.h>

int main() // main function

{

int n1,t; // declaring variable

printf(" Enter an integer :");

scanf("%d",&n1); // taking input

while(n1>0) // iterating over the loop untill the value of n is greater then 0

 {

t=n1%10;

printf("%d",t);

printf("\n");

n1=n1/10;

}

return 0;

}

Explanation:

we taking an integer value n1 and iterating over the loop untill n1>0

suppose n1=1234

then  t=n%10;

means t=1234%10

as % holds reminder means t=4

then print the value of t means print 4

and n1 becomes 123 which is > 0  again condition is checking and same process is follow untill n1>0

output

Enter an integer: 5213
