紀念第一條部落格

Petya started to attend programming lessons. On the first lesson his task was to write a simple program. The program was supposed to do the following: in the given string, consisting if uppercase and lowercase Latin letters, it:

deletes all the vowels,
inserts a character “.” before each consonant,
replaces all uppercase consonants with corresponding lowercase ones.

Vowels are letters “A”, “O”, “Y”, “E”, “U”, “I”, and the rest are consonants. The program’s input is exactly one string, it should return the output as a single string, resulting after the program’s processing the initial string.
Help Petya cope with this easy task.

    Input
    The first line represents input string of Petya's program. This string only consists of uppercase and lowercase Latin letters and its length is from 1 to 100, inclusive.

    Output
    Print the resulting string. It is guaranteed that this string is not empty.

    Examples
 

Input

tour

Output

.t.r

Input

Codeforces

Output

.c.d.f.r.c.s

Input

aBAcAba

Output
.b.c.b
題目分析：
把大小拉丁字母以小寫形式輸出，並去掉母音字母和在每一位字母前增加符號“.”。
程式說明：
先把大寫換成小寫，再用if篩選非母音字母，直接以“.”加字母的形式輸出。
程式實現：

#include "pch.h"
#include <iostream>
using namespace std;
int main()
{
 char*p = new char
 
[100];
 cin >> p;
 for (int i = 0; i < 100; i++)
 {
  if (64 < p[i] && p[i] < 91)
   p[i] = p[i] + 32;
  if (p[i] == 0)
  {
   break;
  }
  if (p[i] != 97 && p[i] != 101 && p[i] != 105 && p[i] != 111 && p[i] != 117 && p[i] != 121)
   cout << "."<<p[i];
  
 }
 delete p;
}
