Pointers in Go
A pointer is a variable that stores the memory address data referenced by another variable. Pointers have the power to mutate data they are pointing to.
Before we begin talking about pointers, let’s learn a thing or two about hexadecimal numbers. A hexadecimal number is a number with base 16. If you are a web developer, then you are using them for a long time, because mostly; colors are represented in hex format. For example, white is represented as #FFFFFF and black as #000000.
In Go, you can save a hexadecimal number in a variable and Go provides a literal expression for that. If a number starts with 0x then it’s a hexadecimal number.
From the above example, we can see that values represented in the hexadecimal system are saved in the decimal system with data type int.
But why we are learning about hexadecimal numbers when we are talking about pointers. Well, let’s talk about the memory address first.
When you are declaring a variable and providing some value (data), the Go runtime will allocate some memory for…
