本弱直接用的 std::string

#include <iostream>#include <cmath>#include <string>#include <algorithm>#include <string.h>using namespace std;int main() {    string a, b;    while (cin >> a >> b) {        if (a.find('.') < a.size()) {            while (a.end() != a.begin()) {                if (*(a.end() - 1) == '0') {                    a.erase(a.end() - 1);                } else                    break;            }                        if(*(a.end()-1) == '.')                a.erase(a.end() - 1);        }        if (b.find('.') < b.size()) {            while (b.end() != b.begin()) {                if (*(b.end() - 1) == '0') {                    b.erase(b.end() - 1);                } else                    break;            }            if(*(b.end()-1) == '.')                b.erase(b.end() - 1);        }            //cout << "|" << a << "|   |" << b <<"|"<< endl;        if (a == b)            cout << "YES" << endl;        else            cout << "NO" << endl;    }    }
