Create/Initialize new object using variables - c++

Question

I am intending to initialize or create a new object using variables.
The error says that i am conflicting declaration.
//instantiate new node object***********************
string peer = "peer";
string pNo = convertInt(addPeerNum); //convert peer number to string to concatenate 2 strings
string NewPeerObject = peer+pNo; << ERROR POINTS TO HERE
nodes NewPeerObject; << ERROR POINTS TO HERE
Error message:
conflicting declaration 'nodes NewPeerObject' <-- last line of error
'NewPeerObject' has a previous declaration as 'string NewPeerObject' <-- 2nd last line
My main point is to create a new object when I add more peers.
If I addpeer 1, it will create a new object 'peer1'
If I addpeer 2, it will be 'peer2' etc.
I am reading in the file which contains
addpeer 1
addpeer 100
addpeer 28
In my program, it reads the file and stores the number in a variable called 'addPeerNum'
and with me doing this, it actually has a different string content of 'NewPeerObject'.
So in this instance, i am actually trying to create 3 new objects.
Is there any way which i will be able to do it?

Answer 1

You cannot have two objects with same name like that. It violates the One definition Rule, naturally the compiler complains.
Just please do yourself a favor and change the name of either of them.

Answer 2

I think that what you are looking for is a kind of dynamically resized array of your objects.
You can use std::list to achieve that kind of behavior.
std::list<PeerObject> list;
PeerObject peer(peer_string);
list.insert(peer);
or a std::map if you want to use your peer string as a key
std::map<std::string, PeerObject> peer_map;
PeerObject peer(peer_string);
peer_map.insert(peer_string, peer);
// .... add more
PeerObject& foundObj = peer_map[a_key];
foundObj.doSomething();
You could also do it with MACROs but only at compile time and you should avoid them if possible.
