读入挂

fastIO读入挂：

 1 namespace fastIO{
 2     #define BUF_SIZE 100000
 3     bool IOerror=0;
 4     inline char nc(){
 5         static char buf[BUF_SIZE],*p1=buf+BUF_SIZE,*pend=buf+BUF_SIZE;
 6         if(p1==pend){
 7             p1=buf;
 8             pend=buf+fread(buf,1,BUF_SIZE,stdin);
 9             if(pend==p1){
10                 IOerror=1;
11                 return -1;
12             }
13         }return *p1++;
14     }
15     inline bool blank(char ch){
16         return ch==' '||ch=='\n'||ch=='\r'||ch=='\t';
17     }
18     inline bool read(int &x){
19         char ch;
20         while(blank(ch=nc()));
21         if(IOerror)return 0;
22         for(x=ch-'0';(ch=nc())>='0'&&ch<='9';x=x*10+ch-'0');
23         return 1;
24     }
25     #undef BUF_SIZE
26 };

fread读入挂：

 1 const int BUF=40000000;
 2 char Buf[BUF],*buf=Buf;
 3 const int OUT=20000000;
 4 char Out[OUT],*ou=Out;int Outn[30],Outcnt;
 5 inline void write(int x){
 6   if(!x)*ou++=48;
 7   else{
 8     for(Outcnt=0;x;x/=10)Outn[++Outcnt]=x%10+48;
 9     while(Outcnt)*ou++=Outn[Outcnt--];
10   }
11 }
12 inline void writell(ll x){
13   if(!x)*ou++=48;
14   else{
15     for(Outcnt=0;x;x/=10)Outn[++Outcnt]=x%10+48;
16     while(Outcnt)*ou++=Outn[Outcnt--];
17   }
18 }
19 inline void writechar(char x){*ou++=x;}
20 inline void writeln(){*ou++='\n';}
21 inline void read(int&a){for(a=0;*buf<48;buf++);while(*buf>47)a=a*10+*buf++-48;}
22 
23 
24 //这句话放到代码中
25 fread(Buf,1,BUF,stdin);
26 fwrite(Out,1,ou-Out,stdout);
27 //样例
28 #include<bits/stdc++.h>
29 using namespace std;
30 typedef long long ll;

39     while(Outcnt)*ou++=Outn[Outcnt--];
40   }
41 }
42 inline void writell(ll x){

52 
53 int main(){

55     int a,b;
56     read(a),read(b);
57     write(a+b);
58     writeln();
59     fwrite(Out,1,ou-Out,stdout);
