#includeOutput: "cdefgh" "de" In this example, we create a wxString object called "str" and assign it the value "abcdefgh". We then use the substr() method to extract two different substrings. The first substring starts at index 2 (the letter "c" in "abcdefgh") and includes all characters after that index. The second substring starts at index 3 (the letter "d") and consists of 2 characters. Both substrings are stored in their own wxString objects, and they are printed to the console. Package library: wxWidgets (a.k.a. wxWindows) is a C++ library that provides a set of classes for GUI programming, file handling, and other common tasks in desktop application development. The wxString class and its substr() method are part of this library.#include int main() { wxString str = "abcdefgh"; wxString subStr1 = str.substr(2); wxString subStr2 = str.substr(3, 2); std::cout << subStr1 << std::endl; std::cout << subStr2 << std::endl; return 0; }
