矩阵乘法
一．程序代码
#include
Script data; node *next; }; class List {
private: node *head; node *tail; int n; public:
List(); void Destroy();
Script Get(int index); void Add(Script data); node * Index(int index); }; List::List() {

}

}

return NULL; }

return -999;
}
class Juzhen { public: int dim; List *list; public:

}
