Algorithm: Writing Names to a File with User Input Validation
1. Initialize a variable num_names to 0.
2. Repeat the following until a valid number of names is entered:
a. Display a prompt to the user, asking how many names they would like to write to a file.
b. Try to read user input as an integer:
- If successful, store the entered value in num_names.
- If the value is greater than 0, exit the loop.
- If the value is not greater than 0, display an error message and repeat the loop.
- If the user enters a non-integer input, catch the ValueError and display an error message.
3. Set the file_name variable to "file_with_names.txt".
4. Open a file named file_name for writing and create a new file (if it doesn't exist) with the "w" mode. Use a context manager to ensure proper file handling.
5. Repeat for i from 1 to num_names:
a. Display a prompt asking the user to enter a name (e.g., "Enter name 1", "Enter name 2", etc.).
b. Read the user's input as a name.
c. Write the entered name to the file, followed by a newline character "\n", to separate each name on a new line.
6. Close the file to save the changes.
7. Display a confirmation message, indicating the number of names that have been written to the file.
8. End.
