对C语言连等式的学习

例子如下

[pgsql@localhost soft]$ cat test1.c
#include <stdlib.h>
#include <stdio.h>

int main()
{
   int a,b,c;
   a = ;
   b =;
   c = ;

   a = b =c;

   fprintf(stderr,"a :%d\n",a);
   fprintf(stderr,"b :%d\n",b);
   fprintf(stderr,"c :%d\n",c);

   return ;
}
[pgsql@localhost soft]$ 

运行：

[pgsql@localhost soft]$ ./test1
a :
b :
c :

得出结论，赋值从右边向左边进行
