Button [4.1 - Codes] Write code to do the following: Remove all the special characters from each code in the array to create a new code - NSC Information Technology - Question 4 - 2023 - Paper 1

To tackle this problem, we need to iteratively process each code in the provided array and filter out special characters while counting how many were removed.

1. Initialize an Empty String: Start with a blank string to hold the new code.
2. Loop through Each Element: Iterate over each code in arrCodes:
   • For each code, loop through its characters.
   • Check if the character is either a letter (a-z, A-Z) or a digit (0-9).
   • If it is, append it to the new string; if not, increment a counter that tracks the number of special characters removed.
3. Store the Results: After filtering the characters for a code, format the output as New code(number of special characters deleted) and add it to the list box lstQ4_1.
4. Output the Results: Ensure that the outputs maintain the specified output format.
