C Program to print the reverse number of a given four-digit number

Here, this program below prints the reverse of any given number in C. We perform the following operations using arithmetic operators.

#include<stdio.h>
int main(){
	int r1, r2, r3, n, rev;
	printf("Enter any four digit number");
	scanf("%d", &n);
	r1=n%10;
	n=n/10;
	r2=n%10;
	n=n/10;
	r3=n%10;
	n=n/10;
	rev=r1*1000+r2*100+r3*10+n;
	printf("Reverse of the given 4 digit numbers= %d", rev);
}

The above code generates its output as below:
