Question

C语言读取文件里的内容，哪位大佬帮忙写下这个程序？

假如文件里有：
ip=192.168.15.2
port=6789
将ip和Port读出来，并分解到两个数组里

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LINE 1024
int main() {
char buf[MAX_LINE];
FILE *fp;
int len;
char *p;
int line=0;
char result[2][50];
if((fp = fopen("d:\\1.txt","r")) == NULL) {
perror("fail to read");
exit (1) ;
}
while(fgets(buf,MAX_LINE,fp) != NULL) {
len = strlen(buf);
if(buf[len-1]=='\n') buf[len-1] = '\0'; /**/
p = strtok(buf, "=");p=strtok(NULL,"=");
strcpy(result[line++],p);
}
fclose(fp);

printf("ip=%s\nport=%s",result[0],result[1]);

return 0;
}
