我们定义一个具有值和名称的变量。变量名称为converted to a memory address，该值存储在该地址中。如果有指针变量，则将另一个变量的实际存储地址存储为一个值。
-
&用于获取变量的内存地址 -
*用于在指针变量存储的地址上获取值。
示例：
func main() {
x := 7
y := &x // creating a pointer variable
p := fmt.Println
pf := fmt.Printf
pf("type of x (non pointer variable) = %T\n", x)
p("value of x (stores actual data) =", x)
p("address of x (memory address where x is located) =", &x)
// invalid operation: cannot indirect x (variable of type int)
// p("value dereferenced by x =", *x)
p()
pf("type of y (pointer variable) = %T\n", y)
p("value of y (stores memory address of x) =", y)
p("address of y (memory address where y is located) =", &y)
p("value at the address stored by y (dereferencing the pointer) =", *y)
}
输出
type of x (non pointer variable) = int
value of x (stores actual data) = 7
address of x (memory address where x is located) = 0xc00001a0e8
type of y (pointer variable) = *int
value of y (stores memory address of x) = 0xc00001a0e8
address of y (memory address where y is located) = 0xc000012028
value at the address stored by y (dereferencing the pointer) = 7
