#includeIn this example, we create a JSON object j that represents the integer 42. We then call the isString() function of j to determine if it is a string. Since the value of j is not a string, the program outputs "The value is not a string". Package library: nlohmann::json#include "nlohmann/json.hpp" using json = nlohmann::json; int main() { json j = 42; if (j.isString()) { std::cout << "The value is a string" << std::endl; } else { std::cout << "The value is not a string" << std::endl; } return 0; }
