In designing large programs how and when should functions be used (check all that apply)?

Which is true about the order in which function parameters are listed in its definition and when called?

Variables (identifiers) listed in the parenthesis during function definition are called

What’s printed? def add(x=20, y=10):               print (x + y) def main():               add(5, 55) main()

What’s printed? def add(x, y):     total =  x+y     return total print(add(100,4))

What’s printed? def func (a, b, d = 7):     return a + b + c + d a, b, c, d = 2, 4, 6, 8  print (func (3, 5))

Variables defined inside a function have the following scope:

What’s printed? def func (a, b, d = 7):     return a + b + c + d a, b, c, d = 2, 4, 6, 8  print (func (a, 5, d = 2))

A function can be useful in creating large scale software systems because, if defined correctly, it presents a useful abstraction for the developer.  This is useful for the developer because  

Functions are required to have the following number of parameters and return statements (check all that apply):
