Just edit deptmain.cpp and leave apparel.h and apparel.cpp as it is to fulfill the requirements
We now want make the deptmain.cpp file more dynamic in how many apparel items to create Note that we don't want a fixed array size; we want to only allocate enough memory for the exact number of items we have. So first your program should ask the user how many items. Then it should create an array of Apparel objects of exactly that size To create a dynamic array, start by declaring the array as a pointer Apparel* list; Then create the array of Apparel objects after asking the size of the array: list = new Apparel [size]; Then use a for loop to ask for the information for each item. Then you will need to call the setters for each field (name, type, color, size and stock) to set the values in the Apparel object. Now, again using another for loop, print out each apparel item in the list using the print function. When done printing, remember to delete the list: delete [1 list; Make C-strings dynamic inside Apparel class To make the program fully dynamic, we should also create the C-strings dynamically. Start by changing the name, type and color member variables to pointer to char: char* name: II and so on.. . Then in the constructor, set these to NULL. This will help determine if these have been previously set to a value name NULL; // and so on.. Now, in the getters, we don't need to copy into a passed in C-string: we can nowExplanation / Answer
//Changed apparel.h file to handle C-String dynamic array instead of char array, u can find code changes with //cheggEA
