#include "rapidjson/document.h" #includeThis example demonstrates how to use `HasMember` to check if a `rapidjson::Document` has a member named `'address'`. If it does not, the program will output `"Document does not have member 'address'"`.int main() { const char json[] = "{\"name\":\"John\", \"age\":30}"; rapidjson::Document doc; doc.Parse(json); if (doc.HasMember("address")) { std::cout << "Document has member 'address'" << std::endl; } else { std::cout << "Document does not have member 'address'" << std::endl; } return 0; }
