Question

I tried to make a function that takes a vector for an argument:

class class0
{
   ...
   ...
}
void function (vector <class0> random_vector)
{
   ...
   ...
}
int main ()
{
   vector <class0> the_vector;
   function (the_vector);
   ...
   ...
}

It worked. I achieved it with a simple experiment. But I don’t know if there is more to know about doing something like this. Is it the same with the other types of arrays? Is this the best way?

So I need is more info about using any type of arrays as an argument for a function.

Answer 1

You can use templates:

template <typename T>
void function (const vector<T>& random_vector)
{
}

which you call like this:

vector<A> vecA;
vector<int> vecI;
function(vecA);
function(vecI);

After re-reading your question, I see you’re more interested in different types of containers.

This can also be achieved with templates:

template <typename container>
void function2 (const container& random_vector)
{
}

which you can call like so:

list<A> lA;
vector<int> li;
function2 (lA);
function2 (li);

Also, you should pass vector types by const & for optimization purposes.
