Hello, I am having a problem with my code in C++/C. I have struggled
for a while and cannot find the solution to the problem...
Here is the compiled..output:
In file included from disk.cpp:8:
disk.h:31:2: invalid preprocessing directive #inlcude
In file included from disk.cpp:8:
****disk.h:89: error: 'ifstream' is used as a type, but is not defined
as a type.*****

17.4.1.2 of the C++ standard. Examples include substituting the <X>

the deprecated header <strstream.h>. To disable this warning use -Wno-
deprecated.
