Hello All,
I wrote a small program which is based on hvector.C in order to store a float vector in a TTree and this tree in a TFile.
If I call the program from root, everything works fine, but unfortunately it does not work if it is called from MSVS.
After calling the program I get the file with the tree which has the branch of integers but not the branch of float vectors.
I assume that I have to include something in order to call it from MSVS.
Looking forward to your feedback.
Regards
Christian
#include <vector>
#include "TFile.h"
#include "TTree.h"
using namespace std;
int main(){
TFile *f= TFile::Open("test.root", "RECREATE");
TTree *t_test = new TTree("test tree","test Tree");
int intNumber;
t_test->Branch("IntNumber",&intNumber);
vector<float> testFloatVector;
t_test->Branch("TestFloatVector",&testFloatVector);
for (int i = 0; i < 200; i++) {
intNumber = i;
testFloatVector.clear();
for (int j = 0; j < 100; ++j) {
testFloatVector.push_back(i*j);
}
t_test->Fill();
}
t_test->Write();
f->Close();
return 0;
}
