編譯錯誤

 LESSON.C(16): error C231: 'wela': redefinition LESSON.C(17): error C141: syntax error near 'while' LESSON.C(17): error C141: syntax error near '1' LESSON.C(19): error C141: syntax error near '=', expected ')' LESSON.C(19): error C129: missing ';' before '<' Target not created 怎么回事呀

void delay=(uint z);    這里多了一個等號呢

謝謝，問題終于解決。太粗心了。
