文件之間的結構

Question

每次嘗試編譯時都會收到錯誤。這可能是愚蠢的，但我無法弄清楚。這是錯誤： aldrbw01 @材：〜/ project5 $使

gcc的-g -c crawler.c -o crawler.o

crawler.c：在函數 '履帶'：

crawler.c：12：錯誤：預期 '{' 前 '*' 標記

化妝：*** [crawler.o]錯誤1

這是用於獲得AP的大小不正確的語法ointer爲struct：

sizeof(struct *wordControl) 
//   ^
// There should be no asterisk between struct keyword and the tag 

星號去的類型名稱後，不是struct和標籤之間：

sizeof(struct wordControl*)
