Here is a step-by-step guide to write a program that counts the number of digits in an integer using a do-while loop: 1. First, you need to take an integer input from the user. You can use the `Scanner` class in Java or `cin` in C++ to do this. 2. Initialize a variable `count` to 0. This variable will keep track of the number of digits. 3. Now, start a do-while loop. The condition of the loop should be `n 0`. This means the loop will continue as long as `n` is greater than 0. 4. Inside the loop, divide `n` by 10 using the `/` operator and assign the result back to `n`. This will remove the last digit from `n`. 5. After the division, increment `count` by 1. This is because each iteration of the loop corresponds to one digit of `n`. 6. The loop will continue until `n` becomes 0, at which point all digits have been counted. 7. Finally, print the value of `count`. This is the number of digits in the original input number. Here is how the code might look in Java: ```java import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int n = scanner.nextInt(); int count = 0; do { n /= 10; count++; } while (n 0); System.out.println(count); } } ``` And here is how it might look in C++: ```cpp #include int main() { int n; std::cin n; int count = 0; do { n /= 10; count++; } while (n 0); std::cout
