c - 文件之间的结构

Question

每次尝试编译时都会出现错误。这可能是一些愚蠢的事情，但我无法弄清楚。这是错误: aldrbw01@timber:~/project5$ make

gcc -g -c 爬虫.c -o 爬虫.o

crawler.c:在函数“crawler”中:

crawler.c:12:错误:“*”标记之前应有“{”

make: *** [crawler.o] 错误 1

这是获取指向struct的指针大小的错误语法:

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

星号位于类型名称之后，而不是位于struct 和标记之间:

sizeof(struct wordControl*)
