Question

Hello experts, im having some trouble with a c++ assignment. I have already written the class cartItem in a previous assignment, with the UML shown in the images below. My issues begin with the LoadArray function, and I reckon if I can get that down I could finish the other functions myself. Ill cut to the chase- how am I supposed to load a file with 3 different data types (string, int, double) into a single array? Thank you.

Here is the assignment, and the file I am reading from is the text file on the left which reads "eggs 3.06...."

I hope this is enough info

Explanation / Answer

We can define a structure to represent one item like below:

struct item

{

string name;

double cost;

int quantity;

};

When loading the data from a file, create a item, and initialize item.name, item.cost, item.quantity and put into an array of item type like below:

ifstream myfile;

item arr[20];

item it;

myfile>>it.name;

myfile>>it.cost;

myfile>>it.quantity;

arr[i] = it;
