运行程序的一处错误`请各位帮看下```100分送上 `````````````在线等
?loop   initial   declaration   used   outside   C99   mode
socket有个这个错误     请问是什么原因
显示错误的代码：
for(int   i=0;i <IndexMate-1;i++){
free(pline[i]);
}


------解决方案--------------------
加上-std=c99参数
即gcc -std=c99 -o c c.c
------解决方案--------------------
#include <stdio.h>
//#include <sys/pes.h>
#include <sys/socket.h>

编译不过去的地方改了一下,没看程序.自己测试一下吧.
