Example 2: Parsing Strings This example shows how to use idCmdArgs to parse string inputs. Suppose we want to write a program that takes in two strings and concatenates them. The program would be executed with the following command: ./concatStrings -a "hello" -b "world" We can use idCmdArgs to parse the string inputs (-a and -b) as follows:c++ #include "idCmdArgs.h" int main(int argc, char* argv[]) { idCmdArgs::ArgumentParser parser(argc, argv); std::string a = parser.getString("-a"); std::string b = parser.getString("-b"); std::string result = a + b; std::cout << "Result: " << result << std::endl; return 0; } ``` Overall, idCmdArgs is a simple and straightforward library for parsing command-line arguments in C++.
