is there any restriction of data type in struct???

[torrengu]

I am a newbe in c++/c. and recently I am trying to read data form a Collada file.so I have to define the data struct to store the parsed data in the memory.
I define the data structure in a head file. but when I compile it ,sth goes wrong.
the whole codes are so long.so I cut part of it, and guess that's enough to show the problem. the head file is listed as follows ,and also the error message.
/-----------------------------------------------------------------/
head file:Collada.h

#include <string>

struct Init_From
{
int num;
};

struct Image
{
Init_From m_Init_From;
};
struct ImagesLibrary
{
vector<Image> m_Images;
};
/---------------------------------------------------------------/

and source file where the winmain function is located:

#include "stdafx.h"
#include "Collada.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
ImagesLibrary *imglib;
while(1)
{


}
return 0;
}

/---------------------------------------------------/

the error message:

d:\program files\microsoft visual studio\myprojects\colladaloader\collada.h(22) : error C2143: syntax error : missing ';' before '<'
d:\program files\microsoft visual studio\myprojects\colladaloader\collada.h(22) : error C2501: 'vector' : missing storage-class or type specifiers
d:\program files\microsoft visual studio\myprojects\colladaloader\collada.h(22) : error C2059: syntax error : '<'
d:\program files\microsoft visual studio\myprojects\colladaloader\collada.h(22) : error C2238: unexpected token(s) preceding ';'
Error executing cl.exe.

/---------------------------------------------------------/

I was wondering if there is any restriction of data type in struct. like complex data types are not available here.

Making a struct creates a new data type. All of your errors are pretty self explanatory. If you edited this with some code tags, I'll look at it more

[torrengu]

thanks for your suggestion. what do you mean by"if you edited this with some code tags,I will look at it more".


maybe I didn't explain it detail enough.

I made the data structure defined in a head file. and within a data structure ,there may be another data strucutre which is defined later in the file. I think that is where the error came from. because when I define a data structure whose elements are all built-in type such as int, float,char ... ,it runs well.

so the words above is my guess. and if I am right, could give me solution,or if I am wrong, could show me what's wrong

vector is in the std namespace. Try std::vector<Image> m_Images; and see if some of the other errors disappear.
