    The compiler doesn't try to determine language from a .h file. The code in the .h file will be compiled as the language of the .c or .cpp file which includes it.

    If the code is C, name the file .c, not .cpp. As you discovered, a lot of valid C code is not valid C++ code.

    Yea i see. So, making the linked list with the c++ tutorial should be better i guess.

    You misunderstood me.
    I was in no way implying that such an endeavour was pointless. I was merely wondering if the point was to learn about DLLs, or learn about syntax trees, or to learn something else, or as part of another project (that perhaps needn't be split into another DLL), or as a plugin to something else etc...

    When someone asks a question the first step is to establish if they are asking the right question, and only after that, actually answer it.

    I recently needed to make a syntax tree; I found the Trie particularly useful and interesting to implement.
