1.1 Button [Question_1_1]
Write code to validate the information entered by the user as follows:

- Name and surname

The input must contain at least one space to be valid. If the input is not valid, display a message to indicate the specific error using a dialog box.

- ID number

The asterisk character (*) next to the text box indicates that the field may not be left blank. An ID number must consist of 13 digits to be valid. If the ID number field does not contain any information or the ID number that was entered does not consist of 13 digits, display a message to indicate the specific error that occurred using a dialog box.

If the contents in both fields are valid, the label displaying the welcoming message must be set visible.

Example of message if no space was entered in the name-surname field:
The name-surname field does not contain a space.

Example of message if the ID number field was left blank:
An ID number must be entered.

Example of message if the ID number that was entered does not consist of 13 digits:

The final purchase amount for today must be entered in the text box.

The program must grant the following benefit towards the holder of the type of loyalty card selected in QUESTION 1_2:

- Immediate discount (DI):
1.5% discount must be granted on the purchase amount.

- Donation towards charity (CH):
An amount of R3 will be donated to a charity organisation for every R100 or part of R100 spent by the loyalty card holder.

Display a message describing the benefit granted depending on the type of loyalty card.

Example of output if the code of the loyalty card is DI and the purchase amount is R1 200:
Enter your final purchase amount for today 1200

NOTE: The discount amount must be displayed as a currency with two decimal digits.

Example of output if the code of the loyalty card is CH and the purchase amount R230:

1.3 Button [Question 1_3]
The customer's D number entered in QUESTION 1_1 and the type of loyalty card selected in QUESTION 1_2 are required to compile the loyalty card number. A loyalty card number consists of three parts. Each part of the number must be compiled as follows and displayed in the components provided:

Part 1:
The first part of the loyalty card number consists of either the letter B if the business card check box was not selected, followed by the first three digits of the customer’s ID number.

Part 2:
A string called charString, which contains the following 10 characters, has been supplied as part of the code provided:

{  }  [  ]  (  )  ^  *  +  -  %

Each character contained in the string represents a digit (0-9). This means that the first character (1) represents the digit 0, the second character (2) the digit 1, and so on.

This part of the loyalty card number must consist of the last digit from the customer’s ID number, followed by the character from charString that represents that digit.

Example of this part of the loyalty card number if the customer’s ID number is 880218756084:
4%

Part 3:
This part of the loyalty card number consists of the code representing the type of loyalty card (DI or CH) established in QUESTION 1_2.
