Concept explainers

Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Question

2. Write an if...else statement that
determines whether a variable called
points is outside the range of 9 to 51
(exclusive). If the variable is outside
this range it should display "Invalid
points". Otherwise, it should display
“Valid points".
3. Write an if...else statement that
determines whether a variable called
speed is inside the range of 0 to 200
(inclusive). If the variable is inside this
range it should display "Valid Speed".
Otherwise, it should display "Invalid
Speed".

4. A software company sells game
cartridges for $99. Quantity discounts
are given according to the following:
10 – 19 O 20% discount
20 – 49 O 30% discount
50 – 99 O 40% discount
-
100 +
O 50% discount
Write a program that asks the user
how many games they purchased.
The program should then display the
amount of the discount (if any) and
the total amount of the purchase after
the discount is applied. Don't forget
to add HST.
5. Earlier we wrote a BMI calculator.
Enhance the program so that it
displays a message indicating whether
the person has optimal weight (BMI
between 18.5 and 24.9), is
underweight (BMI is less than 18.5), is
overweight (BMI between 25 and
29.9), or is obese (BMI 30 or higher).
