C语言链表结构体（学习笔记）

#include <stdio.h>


#define LENTEST 100
	// 采取逐步删除的方法求的素数
	//先假设1-100都是素数，然后剔除2的倍数，
	//3的倍数，直到剔除所有的倍数关系 
int main()
{
	int i = 0, j = 0;
	int bop[LENTEST] = {0};

	for(i = 0; i < LENTEST; i++)
	{
		bop[i] = 1;
	}
	
	for(i = 2; i < LENTEST; i++)
	{
		if(bop[i])
		{
			for(j = 2; j*i < LENTEST; j++)
			{
				bop[j*i] = 0;
			}
		}
	}
	
	for(i = 2; i < LENTEST; i++)
	{
		if(bop[i])
		{
			printf("%d ", i);	
		}
	} 
	printf("
");
	
	return 0;	
}

 7     char *p; //4
 8     char T1[4]; //4
 9     double x;//8
10     char T2[4]; //4
11     int y;//4
12 };

14 int main()
15 {  
16     struct bitTest test;
17     memset(&test, 0x0, sizeof(test));

C语言链表翻转

typedef struct flim{
    char title[TSIZE];
    int rating;
    struct film *next;
}Flim;

void reverse2(Flim **head);

{
    if(*head != NULL && (*head)->next != NULL)
    {
        Flim *tmp1 = (*head);
        Flim *tmp2 = (*head);
        Flim *tmp3 = (*head)->next;

        tmp1->next = NULL;
        while(tmp3->next != NULL)
