This is the mirror programewhere user gives a number which is printed in a reverse order .

Reverse.c

#include<stdio.h>

int main(void){
	int n ,newNum, num4,num3,num2,num1;
	printf("Enbter any Four digit number you wanna reverse : ");
	scanf("%d",&n);   // taking number from users
	// finding the each digits of thr number.
	num4 = n/1000;  
	num3 = (n%1000)/100;
	num2 = (n%100)/10;
	num1 = (n%100)%10;

	printf("%d\n%d\n%d\n%d", num4,num3,num2,num1);// printing the numbers in new line

	newNum= (num1*1000 + num2*100 + num3*10 +num4*1); // simple math 
	printf("Reverse of the number is : %d\n",newNum); // printing the reversed num
}
