Unlock the Power of Loops in C++: Reversing an Integer Made Easy

The Magic of Loops

To reverse an integer, we’ll utilize the mighty while loop. This loop allows us to iterate through a sequence of numbers until a specific condition is met. In this case, our condition is n!= 0, where n is the input integer.

The Reversal Process

Here’s how it works:

1. The user inputs an integer, which is stored in the variable n.
2. The while loop kicks in, and with each iteration, we calculate the remainder of n divided by 10. This gives us the last digit of the number.
3. We then add this digit to our reversed_number variable, effectively building the reversed integer.
4. To prepare for the next iteration, we decrease the value of n by a factor of 10.

int n, reversed_number = 0;
cin >> n;

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

cout << "Reversed number: " << reversed_number << endl;

The Final Result

Once the loop has finished iterating, we’re left with the fully reversed integer stored in reversed_number. This value is then printed to the screen for the user to see.
