Part of a project I'm working on involves creating a variable number of objects and naming them incrementally. More specifically, the user should enter an integer and the program should create the specified number of queues, named queue1, queue2, queue3, etc. The following is a sample bit of code:

CODE

cout << "How many queues should be created? ";
int howMany;
cin >> howMany;

for (int i = 0; i < howMany; i++)
{
    createQueue();
}


My problem is not so much with creating the queues, but naming them. I can't seem to figure out how to append a number to a string in order to form a variable name.

Any help would be appreciated. Thanks.

Well, you can't name variables dynamically. but why don't you think of having dynamic memory allocation and using them as array? that also looks similar to what you are saying.
See, you said queue1, queue2, queue3 and I say queue[0],queue[1],queue[2].

I hope this will help you. smile.gif

This is where stringstream is helpful
CODE

#include <sstream>
using namespace std;

...
std::stringstream  val;
val << 5 << "- name";
std::cout << val.str();
