#includeThis program creates a wxString object with the value "The quick brown fox", and then creates a substring of this string using the Mid function to extract the characters starting at index 4 (the fifth character) and with a length of 5 characters. The program then uses the GetChar function to retrieve the character at index 2 (the third character) of this substring, and outputs the result, which is the character 'u'. Package library: This function is part of the wxWidgets library, specifically the wxString class.#include int main() { wxString str = "The quick brown fox"; wxString sub = str.Mid(4, 5); char third = sub.GetChar(2); std::cout << "The third character of the substring is " << third << std::endl; return 0; }
