C++ 代码

#include<iostream>
#include<cstring>
#include<vector>

using namespace std;

string Data;

vector<string> str={
    "Jan","Feb","Mar",
    "Apr","May","Jun",
    "Jul","Aug","Sep",
    "Oct","Nov","Dec"
};

int main(){
    getline(cin,Data);//获取整行string

    string month=Data.substr(0,3);//substr 获取从0位开始3位的字符串

    for(int i=0;i<12;i++){
        if(!month.compare(str[i])) cout<<i+1;   //string1.compare(string2) 比对完整的string1 和 string2
    }

    string day=Data.substr(3);  //获取从第三位开始的子串
    if(day[0]=='0')cout<<" "<<day[1];   
    else cout<<" "<<day;

    return 0;
}

自认为比其他一长段的好理解多了
