Suppose the product contain the C or C++ statementconst float sales_tax = 6.0;declaring that sales tax is a floating-point constant, and initialized to £©¨ . In this case maintenance isrelatively simple. With the aid of a text editor the value£©¨ is replaced by¦¨ , and the code is recompiled.However, if instead of using the constant declaration, the actual£©¨ has been used in the product whereverthe value of the sale tax is involved, then such a product will be extremely difficult to maintain.1.3 Questions1.
