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.
2 #include <nlohmann/json.hpp>
15 std::cout << array_0 <<
'\n';
16 std::cout << array_1 <<
'\n';
17 std::cout << array_5 <<
'\n';
Output (play with this example online): []
["Hello"]
["Hello","Hello","Hello","Hello","Hello"]
