TString str = "Hello, World!";
TString str1 = "Hello, "; TString str2 = "World!"; TString str3 = str1 + str2;
TString str = "Hello, World!"; const char* cstr = str.Data();
TString str = "The quick brown fox jumps over the lazy dog."; if(str.Contains("fox")){ // Do something }Overall, TString provides an efficient and convenient way to manipulate strings in C++ applications, particularly in high-energy physics analysis. It is part of the ROOT package library.
