Explain what a range check is and provide an example.

What will be an ideal response?


When you use a range check, you compare a variable to a series of values that mark the limiting ends of ranges. To perform a range check, make comparisons using either the lowest or highest value in each range of values.

An example would be: You can ask: Is itemQuantity less than 11? If not, is it less than 25? If not, is it less than 51? (If it's possible the value is negative, you would also check for a value less than 0 and take appropriate action if it is.)
