reference in function

[enemy]

Hello, I have:

  ...
 int a=rand();
int b=rand();
int& c=a*b;

and here are problems with declaration (because of the reference)

I tried:

int a=rand();
int b=rand();
int c=a*b;
int &x=c;

And there was error wrong int* to int

Please , how to solve this?

int a = rand();
int b = rand();
int c = a*b;
int *x = &c;//int pointer x = address of c
