How to assign JSON array to a string using the SimpleJSON library in C++

Question

I want to assign a string with a json array. My code is:

JSONArray v;
JSONObject x,y,value;
....
x[L"x"]=new JSONValue((double)(i));
x[L"y"]=new JSONValue((double)(i));
value[L"value"]=new JSONValue((char*)(data));
v.push_back(new JSONValue(x));
v.push_back(new JSONValue(y));
v.push_back(new JSONValue(value));

all[i]->fruits->append(new JSONValue(v)); //error here,fruits is a string type

fruits is a string defined inside all.

I tried using push_back too but Its not working.

I am using simple json libray github.com/MJPA/SimpleJSON/tree/master/src — user1583647

What exactly do you expect "appending" an array to a string to do? It's like saying you want to add 5 to apple. — Nicol Bolas

I would, if I were you, reconsider your choice to use a library that requires such flippant use of new. — Benjamin Lindley

Assuming that fruits is a std::wstring you can use the Stringigy() member of JSONValue to do handle the conversion.

all[i]->fruits->append(JSONValue(v).Stringify());

thanks it worked.do i have to delete any of the object.As i am running in a big for loop my process is getting aborted.I am getting pointed to deallocate(pointer_p,size_type).

For every new there needs to be a delete. At what point you call delete is really up to how you have organized your program and the requirements of the libraries you use.
