STL Classes in header files

[jsteel]

Im trying to create a class with a vector and a list. It gives me 8 errors, starting with error C2143: syntax error : missing ';' before '<', when i try and dclare either in the header file. Ive included <vector> and <list> in the cpp. I can declare them in the cpp as well. Im using VS6. Ive tried it with and without std::.

Thank You

Show your code and the line the error(s) refer to.

#ifndef GRAPH
#define GRAPH

class CGraph;
class CListGraph;
class CMatrixGraph;

class CGraph {
public:
CGraph() { }
...
};

class CListGraph : public CGraph {
public:
CListGraph() { }
CListGraph(int nNumVertices);
...
private:

};

class CMatrixGraph : public CGraph {
public:
CMatrixGraph() { }
CMatrixGraph(int nNumVertices);
...

private:
vector<int> vertices;
};

#endif

Upon running I get these errors which all refer to the last line 'vector<int> vertices';

error C2143: syntax error : missing ';' before '<'
error C2501: 'vector' : missing storage-class or type specifiers
error C2059: syntax error : '<'
error C2238: unexpected token(s) preceding ';'

In your original post, you said you've included <vector>, but in the code there is no #include <vector>. Add it. In your original post you said you tried it with the std::, but in the code there is no std::vector. Add it.

Ive tried all combinations of adding the include and std::. The code I gave is in the header. I have to #include in the cpp file which consists of just a mian method right now. Putting the include in the header doesnt work either.

 

[uolj]

Sure it will. The #include <vector> should go in the header file just below "#define GRAPH". Everywhere you put vector in the header file you should replace it with std::vector. If there is still a problem, post the code with those changes made and the error's with line numbers (and point out which lines are which if you remove parts - don't remove the lines before and after the errors).

That did work. My Bad. I thought I had tried that combination. Thanks a lot.
