The calculation of the bill will be used the following rules: -The bill will be exempted for usage 20m3 and below. -For the next 15m3 is charged at 50cents/m3. -The next 20m3 is charged at 70cents for every additional m3. -The next 25m3 is charged at $1.00 for every additional m3. -Any further m3 is charged at $1.20 for every additional m3. In this case, the input can be up to 200 m3. The system only accepts the numeric(non-negative) values as the input. Other than the accepted value will be rejected by the system with an error message. The output of the system will be the total bill charged. write out equivalence partition (EP) for the above specification.
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.

-The next 25m3 is charged at $1.00 for every additional m3.
-Any further m3 is charged at $1.20 for every additional m3.
In this case, the input can be up to 200 m3. The system only accepts the numeric(non-negative) values as the input. Other than the accepted value will be rejected by the system with an error message. The output of the system will be the total bill charged.
