Creating array of objects

[aruninnova]

I need to create the following structure but I am struggling to do this using json.

{
	"ParentTree": [{
		"Name": "Name3",
		"children": [{
			"Name": "Name2",
			"children": [{
				"Name": "Name1",
				"children": [{
					"Name": "Name0"
				}]
			}]
		}]
	}]
}

I have tried below but unable to get how to add name and children keys dynamically.

json jsonObj;
jsonObj["ParentTree"] = json::array();
for (auto index = 3; index >= 0; index--) {
	jsonObj["ParentTree"].push_back(json::object());
}

Previously it was done using below way without using json:

std::string PResult = "\"ParentTree\":[{";
	for (int j = 3; j >= 0; j--)
	{
		std::string num = std::to_string(j);
		PResult += "\"Name\":\"";
		PResult += "Name";
		PResult +=  num + "\",";
		if (j == 0) break;
		PResult += "\"children\":[{";
	}

	PResult.erase(PResult.length() - 1);

	for (int j = 3; j >= 0; j--)
	{
		PResult += "}]";
	}

You could use JSON Pointers. They allow to define a value with a string like /ParentTree/0/children/0/children/0/Name etc.

Can you provide an example

A brief introduction is given in the README. Here is an example.
