Program for a warehouse

aherald14 (4)
I am trying to create a program in which I can store different materials from our warehouse, for later on search for them either by the name or by the location
For some reason, it is not storing the materials, so once I search for something it does not do anything

Examine material.txt. What does it contain? Is that what you expect?

Add some temporary code at line 130 to print the values of name, location, type, description and quantity. Also print the value of warehouse.good().

In void newmaterial() I am putting the information I want to store in the file "material.txt"

What does warehouse.good() will do?

Also, don't call the main function, ever. It is really bad.

Why is it so bad to call the main function?

It's one way of getting a stack overflow;
It's prohibited in the C++ standard ;
It's straight up bad coding, it is not structured.

I just created another function call homepage
So instead of calling the main function for either entering anew material of searching for one
It will go to the function call homepage

Still, I am not able to store the data I want

I mean actually look at the contents of material.txt. I think you'll find that it looks odd.
If you add the code I suggested, you'll probably find that you aren't reading the file correctly.
