In this tutorial, we are going to explore the code for printing the Hello World! In Golang. Also, we will see by using which package and function we can do this thing.

To print anything in Golang we import the fmt package that includes the various functions to print anything in Golang.

Different function fmt package consists of.

  • Print()

  • Printf()

  • Println()


packageName.functionName(“Thing you want to print”)


  • Step 1 − Import the fmt package after package declaration.

package main // fmt package provides the function to print anything import ( "fmt" ) // this is the function that will get executed by the // compiler first func main() { /* In this program, we are going to print the Hello World! using the Golang language. As to printing anything on the terminal, we need somefunction to do that like printf() in C language. In Golang also we have a Printf() function and the package That includes the fmt that we have imported at the top. */ // here we have passed the string Hello World! that we get // print on the console // \n is used to break the line in the end fmt.Printf("Hello World!\n") //printing using PrintLn function fmt.Println("Hello World!") //Printing using normal Print function fmt.Print("Hello World!\n") }
