Convert json value to int in c++

Question

I'm reading a json value in c++ using

Json::Reader reader

and the value is stored in Json::Value root

This root contains "age" and "id" and I want to convert root["age"] to int.

I tried to convert it to string using .str() but could not get.

Any suggestion?

In jsoncpp they provide helper methods on the Json::Value object. You can merely call the asInt() method on the value to convert it.

int ageAsInt = root["age"].asInt()
