标题:
读文件一行,将内容存入链表
最近要从文件中读些内容,在其他地方用,写到链表里。
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
struct client_t {
char *client;
struct client_t *next;
};
int
main (int argc,char **argv)
{
FILE *fp;
char *str1 = NULL;
char *str2 = NULL;
char *str3 = NULL;
char *str4 = NULL;
char *str5 = NULL;
char *tmp = NULL;
char *string = "helloworld!";
struct client_t *head,*p;
char buff[100] = {0,};
int i = 0;
int j = 0;
j = atoi(argv[1]);
str5 = argv[2];
if ((fp = fopen (str5, "r")) == NULL) {
//if ((fp = fopen ("./cc", "r")) == NULL) {
printf("error!");
return -1;
}
for(i;i<j;i++) {
fgets(buff,100,fp);
}
tmp = buff;
tmp = strtok_r(tmp, "\n",&str4);
str3 = strtok_r(tmp," ", &str4);
head = malloc(sizeof (struct client_t));
head->client = str3;
head->next = NULL;
for(;str2 = strtok_r (NULL, " ", &str4);) {
p = malloc(sizeof (struct client_t));
p->client = str2;
if (head == NULL) {
head = p;
head->next = NULL;
} else {
p->next = head->next;
head->next = p;
}
}
while (head) {
printf("%s ",head->client);
head = head->next;
}
pclose (fp);
return 0;
}
