Example
The example shows the result of push_back for different JSON Pointers.
1 #include <iostream>

3 
4 using json = nlohmann::json;
5 
6 int main()
7 {
8  // create empty JSON Pointer
10  std::cout << ptr << '\n';
11 
12  // call push_back()
13  ptr.push_back("foo");
14  std::cout << ptr << '\n';
15 
16  ptr.push_back("0");
17  std::cout << ptr << '\n';
