Supermarket Pricing Example

Algorithm design:

get_input and give_output are straightforward

(just a few cin and cout statements)

the algorithm for the function price is given by the following pseudocode:

if turnover <= 7 days then

return ( cost * 1.05);

else

return ( cost * 1.10);

Coding:

there are three constants used in this program

const double LOW_MARKUP = 0.10; // 5%

const double HIGH_MARKUP = 0.05; // 10%

const int THRESHOLD = 7; // use HIGH_MARKUP if do not

// expect to sell in 7 days or less
