输入数字的外挂

普通版正负整数：

#include <bits/stdc++.h>using namespace std;typedef long long LL;template <class T>inline bool rd(T &ret){    T x = 0, f = 1;    char ch=getchar();    while (ch < '0' || ch > '9') {        if(ch == EOF) return false;        if (ch == '-') f = -1;        ch = getchar();    }    ret = 0;    while (ch >= '0' && ch <= '9') {        ret = ret * 10 + ch - '0';        ch = getchar();    }    ret = ret * f;    return true;}int main() {    int a, b;    while(rd(a)) {        rd(b);        printf("%d\n", a + b);    }}

fread版本正负整数

#include <bits/stdc++.h>using namespace std;namespace IO {    const int MT = 5 << 20; //5MB    char buf[MT]; int c, sz;    void begin() {        c = 0;        sz = fread(buf, 1, MT, stdin);    }    template<class T>    inline bool read(T &t) {        while(c < sz & buf[c] != '-' && (buf[c] < '0' || buf[c] > '9')) c++;        if(c >= sz) return false;        bool flag = 0;        if(buf[c] == '-') flag = 1, c++;        for(t = 0; c < sz && '0' <= buf[c] && buf[c] <= '9'; c++)            t = t * 10 + buf[c] - '0';        if(flag) t = -t;        return true;    }}using namespace IO;int main() {    int a, b;    begin();    while(read(a)) {        read(b);        cout << a + b << endl;    }}
