Header files

[bell]

for a starter is there an easy way
of telling which header file(s) to add
when u need to use a particluar function
i am using Visual C++ to write a C++ code.

Usually the MSDN doc set on the disk that came VC++ tells you how to link it and what includes are needed.

For example - if you reference calloc() you have to include malloc.h

And, frequently, a lot of related functions are grouped together - in one header file - as in string functions, math functions, etc.

Other functions may be referenced in several different header files -- sprintf() is an example of that

If it's a windows program, all the main functions and structures are stored in windows.h.

Well they are not actually stored in windows.h. When including windows.h a lot of other header files are actually included. That is why there are macros like WIN32_LEAN_AND_MEAN.
