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
题目分析：
把大小拉丁字母以小写形式输出，并去掉元音字母和在每一位字母前增加符号“.”。
程序说明：
先把大写换成小写，再用if筛选非元音字母，直接以“.”加字母的形式输出。
程序实现：
#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;
}
