Reverse int

To reverse an integer in C++, you can follow these steps:

1. Declare a variable to store the original integer and assign it a value.
2. Declare another variable to store the reversed integer and initialize it to 0.
3. Create a while loop that continues until the original integer becomes 0.
4. Inside the loop, extract the last digit of the original integer using the modulo operator (%).
5. Multiply the reversed integer by 10 and add the extracted digit to it.
6. Divide the original integer by 10 to remove the last digit.
7. Repeat steps 4 to 6 until the original integer becomes 0.
8. The final value of the reversed integer will be stored in the second variable you declared.

Here's an example implementation:

#include <iostream>
using namespace std;

int main() {
    int originalInteger, reversedInteger = 0;

    cout << "Enter an integer: ";
    cin >> originalInteger;

    while (originalInteger != 0) {
        int digit = originalInteger % 10;
        reversedInteger = reversedInteger * 10 + digit;
        originalInteger /= 10;
    }

    cout << "Reversed integer: " << reversedInteger << endl;

    return 0;
}

This code prompts the user to enter an integer, then it reverses the integer and prints the result.
