linux 下 gcc 编译，解决 getch 问题
删掉：
#include <conio.h>
加上：
#include <termio.h>
int getch(void)
{
struct termios tm, tm_old;
int fd = 0, ch;
if (tcgetattr(fd, &tm) < 0) {
return -1;
}
tm_old = tm;
cfmakeraw(&tm);
if (tcsetattr(fd, TCSANOW, &tm) < 0) {
return -1;
}
ch = getchar();
if (tcsetattr(fd, TCSANOW, &tm_old) < 0) {
return -1;
}
return ch;
}
