Example

The example shows the result of push_back for different JSON Pointers.

#include<iostream>
#include<nlohmann/json.hpp>
usingjson=nlohmann::json;
intmain()
{
// create empty JSON Pointer
json::json_pointerptr;
std::cout<<"\""<<ptr<<"\"\n";
// call push_back()
ptr.push_back("foo");
std::cout<<"\""<<ptr<<"\"\n";
ptr.push_back("0");
std::cout<<"\""<<ptr<<"\"\n";
ptr.push_back("bar");
std::cout<<"\""<<ptr<<"\"\n";
}

Output:

""
"/foo"
"/foo/0"
"/foo/0/bar"
