Algorithm


1. Start

2. Include necessary header files
   - #include

3. Declare main function
   - int main()

4. Declare variables
   - int number;

5. Prompt the user to enter a number
   - cout << "Enter a number: ";

6. Read the number from the user
   - cin >> number;

7. Print the entered number
   - cout << "You entered: " << number << endl;

8. Return 0 to indicate successful execution
   - return 0;

9. End
