In Golang, Creating An Array Or Slice Variable Involves Location Or Address In Memory.
The syntax of a pointer to a struct is just like any other pointer. Below is a pointer of type string which can store only the memory addresses of string variables. Printing array elements with its positions output :
This Declares Ptr As An Array Of Max Integer Pointers.
To do this you need to initialize a pointer with the memory address of another variable using the address operator as shown in the below example. Thus, each element in ptr, now holds a pointer to an int value. The following example makes use of three integers, which will be stored in an array of pointers as follows −
