My C++ pointers reference

In one of my C++ classes, we went over pointers and references. Because this stuff isn't second-nature to me, I made a little cheat-sheet, which is here if you'd like.

Declare a pointer

int * foo;

Referencify

int foo = 5;
int * bar;
bar = &foo;
// *bar = 5
foo = 6;
// *bar = 6

Dereferencing

int * foo;
*foo = 5;
*foo = 10;

Function pointers

int (*foo)(int int) is a function that returns an integer and takes 2
foo = min;
foo = add;

Declaring arrays

int array[5];

C strings

char a[] = "foo";
