COMP 206 Unit 6: Initialization and Cleanup

Question	Answer
constructor	special member function that initializes class instance
destructor	- constructor's complement - cleans up object when no longer needed -destructs/deletes object
definition block	variables defined at the beginning of a block after opening brace
2 reasons to dispense with definition block	1. reduce duration of variable's availability within scope; reduce chance it will be misused in some other part of scope 2. readability is improved because reader doesn't have to jump back and forth to beginning of scope to know type of variable
lifetime of loop variable	variable lifetime extended to end of scope that enclosed for loop
aggregate	bunch of things clumped together
aggregate types	1. mixed types: structs and classes 2. single type: array
Way in which aggregate type is initialized	- make assignment, and initialization will be taken care of by compiler - elements in assignment must be surrounded by curly braces -all initialization must go through constructor, even if using aggregate initialization
default constructor	- called with no arguments -creates "vanilla object" -used when compiler is told to create object but isn't given any details
