The reason why the compiler is showing the warning is because it doesn't see a name for the variable of type address you defined for the emp struct, even though you do declare something using address on the next line, but I guess the compiler is not smart enough to figure that out. A...
gcc的declaration does not declare anything 是一个很经典的问题 有以下解决方案 1.加上 -fpermissive 2.修改相关头文件次序 3.修改当前变量名 这不一定是程序的问题(O_O)?

3行#define去掉，没有这种定义方式，如果你找到了那三个子程序，要不复制粘贴到主程序，要不就和主程序放在一个目录，程序自己会调用的
