default directory

基本解釋

This default directory is a good first choice.
這個默認(rèn)目錄是理想的首選目錄。
Each SDK version is installed into its own default directory.
每個 SDK 版本都會安裝到它自己的缺省目錄中。
If you cannot find the default directory, create one using the same name.
如果您沒有發(fā)現(xiàn)這個默認(rèn)路逕，請創(chuàng)建一個同名的路逕。

Because I know this program was saved by default into my current folder, my current directory, so dot slash means run the program called a.out that's right here in my current directory not in, like, a out my applications folder or somewhere else.
程序默認(rèn)保存在,儅前目錄下的文件夾，/意味著運行這個名爲(wèi)“a，out“的文件,是我儅前目錄下的文件，而不是應(yīng)用程序文件夾或其他別的地方的。
