Answer 1

因为你定义的sin数组，在定义结束的时候，也就是大括号外面没有加分号

追问

谢谢，加了；把cast改成case，提示测试.C(43): error C141: syntax error near '}'和测试.C(71): error C141: syntax error near 'delay'怎么回事啊 急

追答

之前的语句都漏了分号啊

追问

延时语句最后一个for后也加了；在没掉；啊
显示测试.C(67): error C141: syntax error near 'delay'
delay（x） 好像有问题，uint b改成uchar了，有看出什么吗？
