#includeIn this code, the `inputfile` argument is a pointer to a ROOT file containing the histograms we want to divide. The `histogram1` and `histogram2` arguments are the names of the two histograms we want to divide. The `TH1D* hist1 = (TH1D*)inputfile->Get(histogram1);` and `TH1D* hist2 = (TH1D*)inputfile->Get(histogram2);` lines retrieve the two input histograms from the input file. The `TH1D* resultHist = (TH1D*) hist1->Clone();` line creates a new histogram that will contain the result of the division, and sets its initial values to the values of `hist1`. We then use the `Divide()` method to divide `resultHist` by `hist2`. Finally, we use `resultHist->Draw();` to draw the resulting histogram. Package library: ROOT#include void divideHistograms(TFile* inputfile, const char* histogram1, const char* histogram2) { TH1D* hist1 = (TH1D*)inputfile->Get(histogram1); TH1D* hist2 = (TH1D*)inputfile->Get(histogram2); TH1D* resultHist = (TH1D*) hist1->Clone(); resultHist->Divide(hist2); resultHist->Draw(); }
