/* Description: This program is to accept data entry and then display */
/* the results for a fictitious company. Multiple data */
/* entry to be accepted until operator quits. Data */
/* to be calculated and displayed. */
/* with validation: product number (1 - 9999) */
/* product type (1 - 5) */
/* quantity (1 -50) */
/* cost (5.00 - 900.00) */
/* price (6.00 - 1000.00) */
/* Add 7 functions: main(), menu(), add(), getreal(), */
/* getint(), total(), and show(). */
/* Include category array: 1 = Camping, 2 = Tennis, */
/* (with running totals) 3 = Golf, 4 = Snow sports, */
/* (display totals) 5 = Water sports */
/* Include product description: create new function */
/* getstring() that uses gets() for keyboard input, */
/* new function strcase() to convert desc. first */
/* letter of each word uppercase + balance lowercase, */
/* display new desc. in show(), create 2D array for */
/* showcosts() dept.name */
/* Convert init-costs() & show-costs() to use pointers */
/* Also, modify getstring() and all string functions */
/* Add limits.txt to be used for validation (remove old) */
/* */
