Debugging Tools/Strategies: The Assert Statement

CS1502 has created a general purpose utility class to assist you in programming. (See the class web page, and labs.) One useful method is ASSERT(), which can be used to validate assumptions and conditions.

Precondition: statement that must be true

before the method can begin execution.

Postcondition: statement that must be true

after the method has executed.

Usage:

util.ASSERT(iDenominator!=0,

“Can’t divide by zero!”);

iFraction =

iNumerator/iDenominator;
