get digits

To extract the digits from a number in C++, you can follow these steps:

1. Declare a variable to hold the number.
2. Use the modulus operator (%) to obtain the remainder when dividing the number by 10. This will give you the last digit of the number.
3. Divide the number by 10, discarding the last digit.
4. Repeat steps 2 and 3 until the number becomes zero.
5. Print or store each digit as needed.

Here's an example code snippet that demonstrates this process:

#include <iostream>

int main() {
    int number;
    std::cout << "Enter a number: ";
    std::cin >> number;

    std::cout << "Digits: ";
    while (number != 0) {
        int digit = number % 10;
        std::cout << digit << " ";
        number /= 10;
    }

    return 0;
}

In this code, the user is prompted to enter a number. The program then iteratively extracts the digits from the number using the modulus operator and division. Each digit is printed on the console.

Note: This code assumes that the user will input a positive integer. If you want to handle negative numbers or floating-point numbers, you will need to modify the code accordingly.
