Golang Values Pointers. Pointers are special variables that are used to store addresses rather than values. Its zero value is nil. You can also use pointers to return values from functions by reference, which allows the function to modify a variable outside its scope. Now, the ptr pointer points to the num variable in memory. A pointer holds the memory address of a value. For example, when you create a string, it defaults to an empty string () unless you assign something to it.here are all the zero values:. 0 for all int types; When a pointer is passed to a function, the function can modify the. Var num int = 42. Pointers in go programming language or golang is a variable that is used to store the memory address of another. Slices, maps, channels, strings, function values, and interface values are implemented with pointers internally, and a. Next, let’s look at how using pointers and values affects defining methods on a type. To assign the address of a variable to a pointer, use the & operator. The type *t is a pointer to a t value. This assigns the address of the num variable to the ptr pointer.
