我记得快输用的是递归吧......这样直接printf不就没意思了吗QwQ

递归？怎么个递归法？我觉得重载运算符更好啊。。。而且我总觉得printf在有些时候比putchar更快啊QAQ

SocialZxy commented 5 years ago

void write(int x)
{
    if(x<0) putchar('-'),x=-x;
    if(x>9) write(x/10);
    putchar(x%10+'0');
}

话说你是怎么回复的啊QwQ

@SocialZxy

void write(int x)
{
    if(x<0) putchar('-'),x=-x;
    if(x>9) write(x/10);
    putchar(x%10+'0');
}

像这样：

还有我觉得用递归的话好像比printf更慢呢。。。

以前我测过一次，printf("%s")比putchar更快。。。
