+- If the package is not the `main` package such as `mymath` in section 1.2, nothing will be generated after you execute `go build`. If you need the package file `.a` in `$GOPATH/pkg`, use `go install` instead.
 - If the package is the `main` package, it will generate an executable file in the same folder. If you want the file to be generated in `$GOPATH/bin`, use `go install` or `go build -o ${PATH_HERE}/a.exe.`
 - If there are many files in the folder, but you just want to compile one of them, you should append the file name after `go build`. For example, `go build a.go`. `go build` will compile all the files in the folder.
 - You can also assign the name of the file that will be generated. For instance, in the `mathapp` project (in section 1.2), using `go build -o astaxie.exe` will generate `astaxie.exe` instead of `mathapp.exe`. The default name is your folder name (non-main package) or the first source file name (main package).

 ## go fmt and gofmt
 
-The people who are working with C/C++ should know that people are always arguing about which code style is better: K&R-style or ANSI-style. However in Go, there is only one code style which is enforced. For example, left braces must only be inserted at the end of lines, and they cannot be on their own lines, otherwise you will get compile errors! Fortunately, you don't have to remember these rules. `go fmt` does this job for you. Just execute the command `go fmt <File name>.go` in terminal. I don't use this command very much because IDEs usually execute this command automatically when you save source files. I will talk about IDEs more in the next section.

 `go fmt` is just an alias, which runs the command 'gofmt -l -w' on the packages named by the import paths.
