So, let's go ahead with our project and see how we can carry out this process in Go language. So, you have to add a new project for trimming spaces and have the main.go
file that we're going to put our code in and then we're just going to run it; your screen should look something like this:
To begin, let's imagine that we have a string variable that has some spaces in it:
package main import ( "fmt" "strings" ) func main(){ greetings := "\t Hello, World " fmt.Printf("%d %s\n", len(greetings), greetings) }
In the preceding code snippet, /t
is for tab and we have some space after it. There is hello World and...
