SLG IPC144 Week 9

What is the size of double* ptrPrice; on a 32-bit system?

• 8 bytes

• 4 bytes

• the size of a double

• 32 bytes

Modular Design entails

• separating the program into reusable and self-contained modules.

• making modules highly cohesive and uncoupled.

• simplifying a complex problem by sub-dividing it into individual aspects.

• making modules highly coupled.

Did you understand last week's lecture on Functions?

• I fully understood. Functions are easy.

• Not at all. Prob gonna drop.

• I think so.

• Mostly, but I still have a few questions.

Did you understand last week's lecture on Pointers?

• I fully understood Pointers. So far Pointers are easy.

• Not at all. Probably gonna drop cause of pointers.

• I think so.

• Mostly, but I still have a few questions.

In Modular Design, Cohesion describes

• the degree of interrelatedness of a module with another module

• how focused a module is at performing only a single task

• the degree of interrelatedness of the datatypes within a module

• how focused a module is at saving memory

In Modular Design, Coupling describes

• the degree of interrelatedness of a module with another module

• how focused a module is at performing only a single task

• the degree of interrelatedness of the datatypes within a module

• how focused a module is at saving memory

The C language supports modular design through the use of

• Structures

• Functions

• Pointers

• Arrays

Write a function prototype called power that takes two integer parameters called base and exponent, and returns an integer.

(Hint: Don't forget the semi-colon)

Call a function called power that takes two arguments

called base and exp (in that order).

Write a function prototype called countDown that takes an integer parameter called n, and returns nothing.

(Hint: Don't forget the semi-colon)
