Step 1
Button [1.1 - Calculate thickness of slices]
Answer
To calculate the thickness of the slices, follow these steps:
-
Declare Variables:
- Declare an integer variable for the number of slices (
numberOfSlices) and a real variable for the thickness (thicknessOfSlices).
- Declare an integer variable for the number of slices (
-
Load Image:
- Use a function to stretch and display the pre-loaded image in the
imgQ1_1component.
- Use a function to stretch and display the pre-loaded image in the
-
Retrieve Data:
- Extract the number of slices from the
spnQ1_1spin edit component.
- Extract the number of slices from the
-
Calculate Thickness:
- Implement the formula for thickness:
-
Format Output:
- Display the calculated thickness in
lblQ1_1. Ensure it is formatted to two decimal places. - Use formatting functions to achieve this.
- Display the calculated thickness in
This process ensures that the thickness of the slices is accurately calculated and displayed based on the user's input.
Step 2
Button [1.2 - Calculate change]
Answer
For this part, we need to calculate the change based on the amount offered:
-
Declare Constants and Variables:
- Set a constant
BREAD_PRICEto 12.90. - Declare a variable for the amount offered (
amountOffered).
- Set a constant
-
Retrieve Amount:
- Extract the amount from the input edit box. Ensure it's converted to a float.
-
Calculate Change:
- Check if
amountOfferedis greater than or equal toBREAD_PRICE:- If true, calculate the change:
- Display the change on the panel as currency.
- Else, display the message "Insufficient amount offered" on the panel.
- Check if
Step 3
Button [1.3 - Multiples of 10]
Answer
For this section, we will find multiples of 10 within a specific range:
-
Counter Initialization:
- Initialize a counter to store multiples of 10 (e.g.,
count= 0).
- Initialize a counter to store multiples of 10 (e.g.,
-
Loop Setup:
- Create a loop to execute 10 times. Inside the loop:
- Generate a random number between 50 and 100.
- Display the random number.
- Check if the random number is a multiple of 10. If it is, increment the counter.
- Create a loop to execute 10 times. Inside the loop:
-
Display Result:
- After the loop ends, display the counter's value along with a relevant message.
Step 4
Button [1.4 - Hidden security code]
Answer
To compile the hidden security code from sParagraph:
-
Initialize Loop:
- Loop through the characters of
sParagraph(from index 0 to the length of the paragraph). - Ensure the security code length is less than 8 characters.
- Loop through the characters of
-
Character Check:
- For each character, check:
- If the character precedes 't' in
sParagraph, add it to thesecurityCode. - If the character at the index preceding a space isn't ' ', ignore it.
- If the character precedes 't' in
- For each character, check:
-
Output Security Code:
- After constructing the security code, convert it to uppercase and display it in
editQ1_4.
- After constructing the security code, convert it to uppercase and display it in
