Why? Because that block identifies a set of things that I'm going to do if the test is true.
为什么呢?这是因为这一块指令,指定了一系列的要进行的操作,如果测试为真的话。
All right, if this is purely a test of, if this is true do this otherwise I don't care, I don't need the ELSE clause in there to identify it. All right?
好,如果这真是一个测验,用来测试如果是真的那么进行一些操作,否则的话我不在乎,那么我不需要ELSE语句,来进行声明了对不对?
