#includeIn this example, the code loads a YAML file and checks if the root node is a map or not using the IsMap property. If it is a map, the output will be "The YAML node is a map" and if it is not a map, the output will be "The YAML node is not a map". The package library used here is the yaml-cpp library.#include int main() { YAML::Node node = YAML::LoadFile("example.yaml"); if(node.IsMap()) { std::cout << "The YAML node is a map." << std::endl; } else { std::cout << "The YAML node is not a map." << std::endl; } return 0; }
