Pointers
Let’s learn about pointers in Go.
Pointers in Go
Go has support for pointers but not for pointer arithmetic, which is the cause of many bugs and errors in programming languages like C. A pointer is the memory address of a variable. We need to dereference a pointer in order to get its value— dereferencing is performed using the *
character in front of the pointer variable. Additionally, we can get the memory address of a normal variable using an &
in front of it.

The following diagram shows the difference between a pointer to an int
and an int
variable.
