HintAnswer
a routine that may or may not return a value
a way of representing the sounds made by a musical instrument
a component of a vector graphic such as a line, rectangle or circle

without guessing a solution before confirming it
when a program does not compile because of syntax or lexical errors
updating a program to correct faults or improve features
