nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer, BinaryType >::basic_json | ( | size_type | cnt,

  Constructs a JSON array value by creating cnt copies of a passed value. In case cnt is `0`, an empty array is created. Parameters
  [in] | cnt | the number of JSON copies of val to create
  [in] | val | the JSON value to copy
  Postcondition `std::distance(begin(),end()) == cnt` holds. Complexity Linear in cnt. Exception safety Strong guarantee: if an exception is thrown, there are no changes to any JSON value. Example The following code shows examples for the basic_json(size_type, const basic_json&) constructor. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create an array by creating copies of a JSON value 9 json value = "Hello"; 10 json array_0 = json(0, value); 11 json array_1 = json(1, value); 12 json array_5 = json(5, value); 13 14 // serialize the JSON arrays 15 std::cout << array_0 << '\n'; 16 std::cout << array_1 << '\n'; 17 std::cout << array_5 << '\n'; 18 } Output (play with this example online):
      []
      ["Hello"]
      ["Hello","Hello","Hello","Hello","Hello"]
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/basic_json__size_type_basic_json.cpp -o basic_json__size_type_basic_json
