The compiler is saying "no such file" about a header file I am including in main

Question

In my C++ project I included a file "Btree.h"

In main i wrote:

#include "Btree.h"

I am getting a compilation error: "no such file or directory"

the project is at https://onlinegdb.com/tI-Qdyuye

Answer 1

It looks like you've already solved the issue if Iook at the linked project.

Just a note: I've never seen anyone use a space in an include file name before. It's good to know it works. :)

However, this could make your life harder in some situations, so I'd recommend not putting spaces into file names. Use e.g. "IntQueue.h" instead.

sorry--wrong link--no, I have not resolved it

You will learn that the compiler is correct 99.999% of the time. :)

It's right again: you cannot include "Btree.h" because you have no such file. Your file is called "BTree.h" (capital 'T' instead of lower case 't').
If you click on the ellipsis (three dots) next to the file name, you can rename the file to have the correct name: "Btree.h".

Note, after this you will have more compilation issues, but the include line now works. :)

The next compilation issue is due to the INT_MIN not being defined in the C++ <limits> header, but the C header file <climits> (or <limits.h>)

In the destructor of Stack, you must not specify the size when you delete the allocated memory:

delete[] bottom;

After this, your code would compile. I'll leave you to have fun with any further issues you find (e.g. #pragma once is twice in Stack.h and doing the conversion of your containers to generic containers / templates)

Have fun! :)

Answer 2

your C file:  #include "Btree.h", but your h filename is BTree.h.( Match case? )

Answer 3

#include <Btree.h>
