    Question struct problem

    I'm having some problems defining a structure, can anyone help

    this bit is in the header file

    Code:
    #include <string>
    
    
    struct netData{
    public:
    	unsigned short int time;
    	unsigned short int dTime;
    	string path;
    	float prob;
    	float conc;
    	bool alarm;
    	netData *nxt;
    };
    for some reason the compiler doesn't like me putting a string declaration into a struct. these are the errors generated.

    c:\work\programming\nettest\nt.h(40) : error C2146: syntax error : missing ';' before identifier 'path'
    c:\work\programming\nettest\nt.h(40) : error C2501: 'string' : missing storage-class or type specifiers
    c:\work\programming\nettest\nt.h(40) : error C2501: 'path' : missing storage-class or type specifiers

    string is the std namespace.

    Try:
    Code:
    std::string path;
    There is no greater sign that a computing technology is worthless than the association of the word "solution" with it.

    Thanks

    I did include the std namespace in the main file, but overlooked that the header file would get prcessed before encountering that bit

    as Homer would say DOHHH

    It shouldn't matter in what order and where header files are included. Therefore keep in mind to prefix std:: to std namespace things in headers.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    I prefer to always type std::string. Then I don't have to worry about it.

    You certainly don't want to put
    using namespace std;
    inside a .h file.

    Anyone using your header file would get the whole std namespace whether they wanted it or not.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    struct netData{
    public:
    ...
    };
    structs are public by default.
