Question

I need help with a group of questions based on Microsofts Visual Basic 2012 8th edition.

Chatper 6 knowledge check:

8) Using a compound operator, write an assignment statement to increment the value in intAmount by 7.

9) Using a compound operator, write an assignment statement to decrease the value in intCounter by 4.5.

10) Using a compound operator, write an assignment statement to increment the value in IntQuantity by 10.

11) Write a top-controlled Do Until loop with an empty body that would continue until intValue is greater than 19.

Explanation / Answer

8) Using a compound operator, write an assignment statement to increment the value in intAmount by 7.

Compound assignment statements first perform an operation on an expression before assigning it to a programming element.

So, the solution is: Amount += 7;

This statements first evaluates the expression, Amount+7, and then assigns the result to Amount. This is pretty much equivalent to the equation: Amount = Amount + 7;

9) Using a compound operator, write an assignment statement to decrease the value in intCounter by 4.5.

The solution is: Counter -= 5;

This statement is equivalent to the equation: Counter = Counter - 5;

10) Using a compound operator, write an assignment statement to increment the value in IntQuantity by 10.

Quantity += 10; will increment the Quantity by 10, and will assign the result to Quantity.

11) Write a top-controlled Do Until loop with an empty body that would continue until intValue is greater than 19.

Do

Value += 1 'Increments the Value by 1, which keeps the loop moving.

Loop Until Value > 19
