Hi all,
I tried to declare a c++ struct like following in a header file; I
want to include
this header file in other files to create and access this struct.
------
1 #ifndef _SEARCHDATA_H_
2 #define _SEARCHDATA_H_
3
4 #include <vector>
5 #include <list>
6
7 typedef struct searchIterInfo searchIter;
8 struct searchIterInfo {
9 searchIterInfo ():
10 contPts(0), //continuous trial points
11 contFvs(0), //fv for cont points
12 contFerrors(0), //std errors for cont points
13 gradients(0), //list of gradients
14 intPts(0), //evaluated int points
15 intFvs(0), //function values for int points
16 intFerrors(0), //errors for int points
17 intPtList(0), //the monotone list of points
18 simList(0), //the simplex list
19 seedVals(0), //the seed values
20 hMtx(0) {}; //the estimated hesian matrix
21
22 vector< vector<double> > contPts;
23 vector<double> contFvs;
24 vector<double> contFerrors;
25 vector< vector<double> > gradients;
26 vector< vector<int> > intPts;
27 vector<double> intFvs;
28 vector<double> intFerrors;
29 list<int> intPtList;
30 list<int> simList;
31 vector<double> seedVals;
32 vector< vector<double> > hMtx;
33 int iterID; //the sample path index
34 double sampleSize; //the sample size for this sp
35 };
36 #endif

I got compiler errors:

I am a beginer of c++ programming, so anyone pls help me.
Thanks a lot.
