Hello World in Golang

#BackCoding

Now, first add the package main in your program:package main

Every program must start with the package declaration. In Go language, packages are used to organize and reuse the code. In Go, there are two types of program available one is executable and another one is the library. The executable programs are those programs that we can run directly from the terminal and Libraries are the package of programs that we can reuse them in our program. Here, the package main tells the compiler that the package must compile in the executable program rather than a shared library. It is the starting point of the program and also contains the main function in it.

After adding main package import “fmt” package in your program:import( “fmt” )

Here, import keyword is used to import packages in your program and fmt package is used to implement formatted Input/Output with functions.

Now write the code in the main function to print hello world in Go language:
func main() {
fmt.Println(“!… Hello World …!”)
}

In the above lines of code we have:

func: It is used to create a function in Go
language.

main: It is the main function in Go language, which doesn’t contain the parameter, doesn’t return anything, and call when you execute your program.

Println(): This method is present in fmt package and it is used to display “!… Hello World …!” string. Here, Println means Print line.
