题目描述

常规做法，但是挺麻烦的，要学习新方法。

样例

#include<iostream>
using namespace std;
int main()
{
    int x;
    cin>>x;
    if (x==61)   
    cout<< "Brasilia" <<endl;
    else if(x==71) 
    cout<< "Salvador" <<endl;
    else if(x==11) 
    cout<< "Sao Paulo" <<endl;
    else if(x==21) 
    cout<< "Rio de Janeiro" <<endl;
    else if(x==32) 
    cout<< "Juiz de Fora" <<endl;
    else if(x==19) 
    cout<< "Campinas" <<endl;
    else if(x==27)
    cout<< "Vitoria" <<endl;
    else if(x==31) 
    cout<< "Belo Horizonte" <<endl;
    else 
    cout << "DDD nao cadastrado" <<endl;
    return 0;
