Short: A pointer is variable, which holds the address of another variable.

For example
int x = 3; \\ stored at memory location x034 for example
int* p = &x; \\ & gets the refernce = address of x, stored in p
\\ p points to x of type int
\\ the address of p itself is different again

This is useful to get at the starting point of an array for example, which is stored consecutively in memory.
