提示錯誤是 139 20 C:\Users\admin\Desktop\work\main1.cpp [Error] cannot convert 'int (*)[2]' to 'const POINT* {aka const tagPOINT*}' for argument '1' to 'void polygon(const POINT*, int)'
uj5u.com熱心網友回復：
錯誤提示很清楚啊。。BOOL Polygon( LPPOINT lpPoints, int nCount )
這是函式原型。第一個引數，應該是一個“POINT”型別的指標，在你的代碼中，second變數，很明顯，是一個int型別的二維陣列，型別匹配啊。。
