Answer 1

144: error: structure has no member named `number'
结构体没有名称为“number”的成员
172: error: `stu' undeclared (first use in this function)
stu没有声明（首次使用时，先声明）
220: error: invalid use of undefined type `struct student'
struct student这个类型没声明
。。。。。。。。。。。。

你双击错误，编译器会自动定位到有错误的代码行，你一条一条改吧
错误其实没这么多，通常是一个错误引发N个
