error: expected expression before ‘struct Linux C/C++编程时常会遇到“error: expected expression before ‘struct’”错误,此错误一般是由未定义的宏(宏里套宏)或参量引起,导致编译器判断当前语句为非法语句,可能有如下几种情况。 1、缺少ioctl.h头文件 调用ioctl函数,用到参数VIDIOC_QUERYCAP时无法编译通过。 ...

The "new" keyword hints at this being C++. In C++ the "struct TYPENAME" construct is largely obsolete, you can simply use TYPENAME instead. The C way of typedefing a type name from a named struct is implicit in C++. node*NewNode(intdata){ node* pnode =newnode; pnode->data = data...

把typedef去掉！struct stu{int length;int width;int height;char name[9];}student[10][10];int main(){ 后面的 maxnum=student[i][0];minnum=student[i][0]; 这两句没有看懂，两个不同的类型数据，怎么能赋值？
