WIN32: *.c *.cpp compilation difference ???

[guenter]

Hello,

My Question is about what's the difference at naming my Sourcefiles *.c or *.cpp ?
I'm using VC++ 6.0.

I've written an Win32 Application that compiles fine using the *.c file-extension.
Just after renaming the file to *.cpp I get some strange errors:

error C2440: '=' : could not convert 'void *' to 'struct linetranslateoutput_tag *'
at this Line: 'LPLINEDEVSTATUS pLineDevStatus = LocalAlloc(LPTR, BIGBUFF);'

The project ( compiler switches etc.) are exactly the same

any hints welcome

thanks
guenter

C++ does much stricter type-checking that plain-old C.

I recommend that you read Stroustrup's "The C++ Programming Language".
