Hey guys in this post, we will discuss the functions and how to call functions in Golang with easy to understand examples.
Table of Contents
1. Create a directory
mkdir go-workspace
2. Move inside the directory
cd go-workspace
3. Create an empty file
code Functions.go
Keyword code
represents Visual studio code, it will open the file inside the Visual studio code.
Note: I will be using Visual studio code for writing code but you can use any other text editors or IDEs for writing code.
4. Write the Code
package main
import "fmt"
func main() {
subFuction()
}
func subFuction() {
fmt.Println("Calling another function inside main() function!")
}
- A function is a group of statements that exist within a program for the purpose of performing a specific task
- In Golang we use
func
keyword to create functions - In fact, the
main()
method itself is a function - We can call functions inside any other functions, any number of time.
5. Run the Code
To run the program, open the command prompt and execute the following command
PS C:\workspace\go lang workspace> go run .\Functions.go
Calling another function inside main() function!
