第一次作业运行结果和给的答案不一样
为什么我运行的结果是0行代码#include <io.h>

} 如果你也用 VS2015 ,那么,第50行,是一定要改的,否则,输出为 0 行,
你的程序我运行了,只要将第 50 行改为 .cpp,即:
if((handle = _findfirst(strcat(thePath, "/*.cpp"), &fa)) != -1L),就没有问题了,输出 103 行 风过无痕1989 发表于 2020-12-1 23:32

哇!!!太谢谢你啦,我用的是devc++,我回去就试试看! 相识0919 发表于 2020-12-2 10:04

DEV++ 在编译时会让你保存,你若对保存的名字不作反应的话,它默认就是C++程序
只有保存时,加一个 .c ,保存的才是C程序 风过无痕1989 发表于 2020-12-2 10:10

嗯嗯嗯,好的,我试了一下可以啦,感谢 相识0919 发表于 2020-12-2 21:04
