nlohmann::basic_json::basic_json ( size_type  count,
const basic_json value 
)
inline

Constructs a JSON array value by creating count copies of a passed value. In case count is 0, an empty array is created. As postcondition, std::distance(begin(),end()) == count holds.

Parameters
[in]countthe number of JSON copies of value to create
[in]valuethe JSON value to copy
Complexity
Linear in count.
Example
The following code shows examples for the basic_json(size_type, const basic_json&) constructor.
1 #include <json.hpp>
2 
3 using namespace nlohmann;
4 
5 int main()
6 {
7  // create an array by creating copies of a JSON value
8  json value = "Hello";
9  json array_0 = json(0, value);
10  json array_1 = json(1, value);
11  json array_5 = json(5, value);
12 
13  // serialize the JSON arrays
14  std::cout << array_0 << '\n';
15  std::cout << array_1 << '\n';
16  std::cout << array_5 << '\n';
17 }
