你的伪随机数的种子初始总是固定的,就是这个函数:
int my_rand()
{
static unsigned long seed = 1;
seed = seed*1103515245+12345;
return (unsigned int)(seed/65536) % 32768;
}
先加个头文件#include <time.h>
再将static unsigned long seed = 1;
改为static unsigned long seed = (unsigned long)time(0);
这样就不会出现同样的序列了
先不说内容，你的格式就很难看，要增加语句的可读性格式是十分重要的，自己要注意这方面的意识。
得改变随机数的种子，下面的方法可以做到：
srand(time());
最起码写点注释！
