Hello I have two files Principal.cpp and Individuo.h, I want to create a hundred objects of Individuo, what can I do?
Thanks

There are 5 of these

> vector<string> operacion={"+","-","*","/","^"};
There are 5 of these as well.

I make 25 possible permutations.

How do you get to 100?

Let's start here, with something that would actually compile?

	vector<Individuo> individuo;
	for (int i = 0; i < 5; i++)
	{
		for (int j = 0; j < 5; j++)
		{
			individuo.push_back(Individuo(fact[i], operacion[j]);
		}
	}


As salem c mentioned, if you choose 1 from each set, you can have 25 unique pairs. Anything more than that, and you're going to have repeated elements. But of course you still can make 100 elements worth.

Here is 100 objects of individuo.

Every individuo have random sctrings of fact and strings ...

Is that an observation or requirement?
If the latter, why did you not say so in the first post?
