What is Stepwise Refinement?
Stepwise Refinement is a top-down design process in which the programmer starts with the overall goal of the program and continually breaks down the design into sub-functions.
What is this called?
The capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged to accommodate that growth
Scalability

D: Functions cannot make calls to other functions within the same program.
D
Which of the following is an example of abstraction?

B: using logic symbols like <and>
C: Numbers are converted from one base to another
D: There is an error in the code
