#includeint main() { TFile *file = new TFile("output.root", "RECREATE", "", 9); // write some data to the file file->Write(); // save the contents to a file on disk file->Save(); // close the file file->Close(); return 0; }
#includeBoth of these examples use the TFile class from the ROOT library and call the Save() function to write the contents of the file to disk. The first example specifies a compression level of 9, while the second example uses no compression. The package library for TFile Save is ROOT, which is an open-source software framework for high-energy physics data analysis. ROOT provides a wide range of tools and libraries for data analysis, including tools for data visualization, statistical analysis, and machine learning.int main() { TFile *file = new TFile("output.root", "RECREATE", "", 0); // write some data to the file file->Write(); // save the contents to a file on disk file->Save(); // close the file file->Close(); return 0; }
