Decision making structures require that the programmer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false. Following is the…

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations. Go language is rich in built-in operators and provides the following types of operators − This tutorial explains arithmetic, relational, logical, bitwise, assignment, and other operators one by one. Arithmetic Operators Following table shows all the arithmetic operators supported…

Constants refer to fixed values that the program may not alter during its execution. These fixed values are also called literals. Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal. There are also enumeration constants as well. Constants are treated just like…

A variable is nothing but a name given to a storage area that the programs can manipulate. Each variable in Go has a specific type, which determines the size and layout of the variable’s memory, the range of values that can be stored within that memory, and the set of operations that can be applied…

In the Go programming language, data types refer to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted. The types in Go can be classified as follows − Sr.No. Types and…

We discussed the basic structure of a Go program in the previous chapter. Now it will be easy to understand the other basic building blocks of the Go programming language. Tokens in Go A Go program consists of various tokens. A token is either a keyword, an identifier, a constant, a string literal, or a…

Before we study the basic building blocks of Go programming language, let us first discuss the bare minimum structure of Go programs so that we can take it as a reference in subsequent chapters. Hello World Example A Go program basically consists of the following parts − Let us look at a simple code that…

Local Environment Setup If you are still willing to set up your environment for Go programming language, you need the following two software available on your computer − Text Editor You will require a text editor to type your programs. Examples of text editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim…

Go is a general-purpose language designed with systems programming in mind. It was initially developed at Google in the year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is strongly and statically typed, provides inbuilt support for garbage collection, and supports concurrent programming. Programs are constructed using packages, for efficient management of dependencies.…
