# Program to find reverse of the number

In this example, We will learnt to find reverse of any number using C++ programming language.

To understand this example, We must have knowledge on following topics

To do this program, First we will take integer from user.

Then, We will loop number checking condition that number is equal to zero.

We will find remainder dividing by 10 and set to remainder variable

And also We will multiply previous reverse variable by 10 and add that remainder that we just obtained above. On this way we will find the reverse of any number using c++ programming langauge.

Let’s look an example to make clear concepts.

```
#include <iostream>
using namespace std;
int main() {
int n, rev = 0, rem;
cout << "Enter an integer: ";
cin >> n;
while(n != 0) {
rem = n % 10;
rev = rev * 10 + rem;
n /= 10;
}
cout << "Reversed Number = " << rev;
return 0;
}
```

The output of above program is

```
Enter an integer: 123
Reverse Number = 321
```
