这是代码
#include <iostream>
using namespace std;
struct Node{
int data;
Node *next;
};
Node *head;
`insert function takes a number as argument`
void insert(int a)
{
Node *temp = new Node();
temp -> data= a;
temp->next = head;
head = temp;
}
void print(void)
{
Node *temp1;
temp1 = head;
while(head != NULL)
{
cout<<temp1->data<<endl;
temp1 = temp1->next;
}
}
**main function**
int main()
{
head = NULL;
int a;
int b;
cout<<"how many elements do you want to insert";
cin>>b;
for (int i = 0;i < b; i++)
{
cout<<"enter a number"<<endl;
cin>>a;
insert(a);
print();
}
return 0;
}
当我输入要插入的数字时,它显示程序已停止工作。我正在尝试将数字插入链表并在每次添加数字时打印它。我检查了许多其他错误,但没有。
答案 0 :(得分:0)
看起来可能是由于其中一条评论所说的无限循环。尝试像这样更新 print
函数中的循环:
void print() {
Node *temp1;
temp1 = head;
// Here, I switched `head` with `temp1`
while (temp1 != nullptr) {
std::cout << temp1->data << std::endl;
temp1 = temp1->next;
}
}
