Function that can accept another function

[jdm1891]

I want to make a class with a function, that can accept the function of another class, with a vector of arguments. And perform the function with each of those arguments.

for example:

int double(int a)
{
    return 2*a;
}

and then it would be used like this:
doFunction(double(), std::vector<int> {2,5,4,6});

and it would return a vector of outputs(4,10,8,12)

I am unsure of of how to do this in a way it could be used for any function.
