Introduction The interface is a concept used in Golang and it helps us get polymorphisms. So we don’t get the inheritance, we don’t need inheritance, we don’t need overriding. We can use interfaces to do the same thing. The interface is a set of method signatures. So by signatures, It …
Introduction Encapsulation The encapsulation provides a lot of different support for encapsulation and keeping private data. But you want to be able to have controlled access to the data. So typically, even if you have private data in some package, you probably don’t want to hide it completely. but you …
Introduction In this tutorial, you’ll understand functions in Go programming. Basically, a function is a group of instructions with a name. And the name is actually optional, but it’s a bunch of instructions that are group together. as we’ll see step by step. The func main(). We’re defining a function …
Introduction In this tutorial we’ll understand Struct in Golang, a Struct is another aggregate data type, another composite data type, as an aggregate type meaning groups together objects of arbitrary data types into one object. The struct is short for structure, by the way, this takes also straight from C. …
Introduction In this tutorial, you’ll understand map implementation of a hash table in Golang. So, a map is exactly a hash table. using the make() function to create a map. So, we have the following example here. We declaring MapVal as a variable, a map variable. So, var MapVal and …
Introduction A hash table is a data structure used in a lot of different languages, and it’s a very useful data structure, it allows you fast access to large bodies of data. Hash table generally contains a key-value pair, so there are a lot of values inside this hash table …
Introduction In this tutorial, we’ll learn the slice data type and it’s a declaration. Slice is a data type and it is a useful data type. the slices use instead of arrays because they are flexible, you can change their size, you can increase them in size. The slice is …
Introduction In this article, we’ll discuss arrays implementation in Go programming. So, the array is where you take a bunch of a fixed-length series of elements of a chosen type. So, you can make an array of bytes, you can make an array of integers, an array of floats with …
Introduction In this article we’ll understand garbage collection and deallocating memory, So it can be hard to determine Because it is appropriate to deallocate a variable. when you can only deallocate a variable when you know the variable is no longer in use. If you don’t want to deallocate a …
Introduction In this article, we’re going to learn about basic data types, and we’re going to start with Pointers. So, let’s go straight to these Pointers and understand step by step. What is a Pointer? The pointer is an address to some data in memory. So, every data variable is …
