performing a calculation in the wrong part of a control construct
subject			fact

performing a calculation in the wrong part of a control construct	has definition A common defect in which the program performs an action when it should not, or does not perform an action when it should
	has testing strategy design tests that execute each loop zero times, exactly once, and more than once ensure that anything 'bad' or 'unusual' that could happen while looping is made to occur on the first iteration and the last iteration
	is a subtopic of 10.3 - Defects in Ordinary Algorithms
	is typically caused by inappropriately excluding the action from, or including the action in, a loop or if-then-else construct
	is a kind of defect in an ordinary algorithm
	may not be caught using black-box testing, so glass-box testing or inspections may be more effective
defect	has example the absence of code to handle an exception
problem	has solution which will normally entail developing software, although you may decide that it is better to purchase software or to develop a non-software solution
	should be written as a simple problem statement in one or two sentences
