Calling a function with different types

I am working on an assignment in C++ and am having difficulties with a question.

We are given a function that can take anything in as an argument.
We need to call this function, UberFunction, as an int, int*,
int**, and char[].

When I call:

UberFunction(42);

the assignment gives me points for a correct answer. Directly under this I have tried:

int* UberFunction(42);
int** UberFunction;
UberFunction(int*42);

...I have tried just about everything I can logically think of.

Am I missing something? If UberFunction(42) is right for the int part, why isn't UberFunction(int*42) working?

My Code:

void CallUberFunctions() {
  // There is a magic function, called "UberFunction" that is capable of taking
  // anything for an argument. You need to call "UberFunction" with the
  // following types: int, int* int** and char[]
  // You also need to call "OtherUberFunction" in the namespace
  // "uber_namespace" once, with no arguments.
  UberFunction(42);
}

Here is the error:
