我正在创建一个简单的问题。我尝试将学生添加到一个列表中,然后将其拆分为两个列表。我创建了一个将节点添加到列表的通用方法,但它似乎不能正常工作。这是我尝试过的。我做错了什么?
int main()
{
for(int i=0;i<NR_STUDENTS;i++)
{
Student *studToAdd=new Student;
cout<<"Student #"<<i<<endl;
cout<<"Name:";
cin>>studToAdd->name;
cout<<"Grade:";
cin>>studToAdd->grade;
Add(studToAdd);
}
Split();
Print();
}
#include "students.h"
Node *allFirstNode;
Node *admitedFirstNode;
Node * rejectedFirstNode;
void AddNodeToList(Node *firstNode, Student *studToAdd)
{
Node *nodeToAdd=new Node;
nodeToAdd->student=studToAdd;
nodeToAdd->next=NULL;
if(firstNode==NULL)
{
firstNode=nodeToAdd;
}
else
{
Node *temp;
temp=firstNode;
while(temp->next != NULL)
{
temp=temp->next;
}
temp->next=nodeToAdd;
}
}
void addStudent(Student *studentToAdd)
{
AddNodeToList(allFirstNode,studentToAdd);
