- 楼主啊，搞错啦
- 应给是
```cpp
inline int read(){
register int ans=0;register char c=0;register bool f=0;
while(!isdigit(c)) f|=c=='-',c=getchar();
while(isdigit(c)) ans=(ans<<1)+(ans<<3/*这里是3*/)+(c^'0'),c=getchar();
return f?-ans:ans;
}
```

其实不加fread的话这个快读貌似比scanf快不了多少QAQ

@[ziye](/space/show?uid=29832) 大数据的话就会很明显了

10000000个int型
实测scanf 6s左右
cin关闭流同步5s左右
这个快读3s左右
fread不到0.5s

@[ziye](/space/show?uid=29832) scanf和快读之间差别是大吧3s，我又没有说到fread
by ZEROLANE @ 2019-08-05 22:11:09
@[ziye](/space/show?uid=29832) fread加上是要快很多，我也没说不快鸭QAQ

嘤嘤嘤但是只有fread可以进1s其他的都得t鸭
