Pointers
Go has pointers. A pointer holds the memory address of a value.
The type *T is a pointer to a T value. Its zero value is nil.
var p *int
The & operator generates a pointer to its operand.
i := 42 p = &i
The * operator denotes the pointer's underlying value.
fmt.Println(*p) // read i through the pointer p *p = 21 // set i through the pointer p
This is known as "dereferencing" or "indirecting".
Unlike C, Go has no pointer arithmetic.
