C语言：head插入新节点程序无法运行，以下情况如何解决

#include<stdio.h>
#include<stdlib.h>
struct Node
{
    int data;
    struct Node* next;
};
struct Node* head;
void insert(int x)
{
    struct Node* temp = (struct Node*)malloc(sizeof(struct Node));
    temp->data = x;
    temp->next = head;//涵盖head = NULL情况
    head = temp;
}
void print(){
    struct Node* temp = head;
    printf("list is:");
    while (temp != NULL)
    {
        printf(" %d",temp->data);
        temp = temp->next;
    }
    printf("\n");  
}
int main(){
    head = NULL;
    printf("how many numbers?");
    int n,i,x;
    scanf("%d",&n);
    for ( i = 0; i < n; i++)
    {
        printf("enter the number:\n");
        scanf("%d",&x);
        insert(x);
        print();
    }
    
}

代码没有问题，你的编译的命令行有问题
