你见过这样的代码？
刚刚在网上看到这样一段代码，用#define把关键字都替换成一堆下划线，可读性几乎为0。
#include <cstdio> #include <string> #include <stack> #include <algorithm> #include <iostream> #include <cstring> #include <cmath> #include <map> #include <cstdlib> #include <set> #include <queue> #include <deque> #include <vector> #include <cctype> #include <iomanip> #include <sstream> #include <set> using namespace std;

} } } ______________________________________________ 0; } 几乎是跪着看完的…...........
最后编译了一遍发现报错：error: ‘gets’ was not declared in this scope gets(s)。
搜索后发现gets()方法已经不被PAT编译器支持了，修改方法如下：
// gets(str); // 替换成下面 cin.get(str, n); // n为str数组的长度这样就可以正常编译通过了。
