Join David Gassner for an in-depth discussion in this video Getting input from the console, part of Learning Go.
- I've previously described how to use the FMT package…to output and format strings.…The package also has input methods…that you can use to analyze strings:…the scan methods.…These are designed to get input…from the console, files, variables, and other input sources…and automatically separate values from each other…by looking for space characters.…On first appearance, these functions look like…they might be useful for getting user input…in a console application.…In this file, consoleinput.go,…I only have an import statement…and in the main function,…I'll declare a variable named S…and set its type as a string.…
Then I'll use a function of the format package,…named Scanln.…It looks like this: fmt.Scanln.…And then I'll pass in the string variable,…but I'm not going to pass it in by value,…as you typically do.…Instead, I'll pass it in as a reference.…The syntax for that is the name of the variable…with an ampersand prefix.…Now, that function will operate on the same reference…that I declared in the calling function.…
