[C++] Using Structs -- Odd Issue

Question

Been awhile since I've used structs in C++.

Any idea why this isn't working? My compiler is complaining about DataStruct not being a recognized type but Intellisense in VC++ is still able to see the data members inside the struct so the syntax is ok...

Frustating. xD

struct DataStruct
{
    int first;
};



int main(int argc, char **argv)
{   
    DataStruct test;
    //test.first = 1;
}

Answer 1

You need to use struct DataStruct to refer to the struct.

Alternatively, you can typedef it as DataStruct if don't want to use the "struct" everywhere.

Answer 2

Are you sure you are compiling the file as C++? If you compile it as C (i.e. if the file has a .c rather than a .cpp extension), you will have problems.

Answer 3

You are compiling as C code. C requires you to refer to it using the "Struct" keyword or typedef it. C++ does not.
