跨平台的最好方法是fread快读。
```cpp
namespace FastIO {
inline unsigned char nextchar() {
static const int BS = 1 << 22;
static unsigned char buf[BS],*st,*ed;
if( st == ed ) ed = buf + fread(st=buf,1,BS,stdin);
return st == ed ? 0 : *st++;
}
inline uint getint() {
uint ret = 0 , ch;
while( !isdigit(ch=nextchar()) );
do ret = ret * 10 + ch - '0'; while( isdigit(ch=nextchar()) );
return ret;
}
}
using FastIO::getint;
```
这是不考虑负数的读入int版本。
