c++ - 带有指针的循环不起作用

Question

我有一个问题，我正在尝试创建一个列表，该列表删除持有最高值(value)的数字，或者如果该值在列表中最高，则删除具有相同值的所有数字。感谢您提供任何类型的提示。

// n,n1,head,next - are pointers
int j = 0; //this number helps to put pointer forward by one place
while(n!=0){//should go through every digit of the list
    if(head == 0){
        cout << "list is empty" << endl;
    }
    else{
        n = head;
        n1=0; // n1 and n are pointers
        while(n!=0){
            if(n->sk == maxx){//searches for maximum digit in the list
                break;
            }
            else{
                n1=n;
                n=n->next;
            }
        }
        if(head == n){
            head = head->next;
        }
        else{
            n1->next = n->next;
        }
        delete n; // deletes the pointer holding the highest value
    }
    n = head; //problem is here or somewhere below
    j++;
    for(int i=0; i<j;i++){ // this loop should make the pointer point to the first
        n = n->next;       // number, then the second and so on until the end of list
    }                      // and all the numbers inside the list with the value that
}                      // equals "maxx" should be deleted

您应该取消对指针的引用。现在，您正指向他们的地址。看看这是否有助于解决您的问题。
