我是靠谱客的博主紧张战斗机，最近开发中收集的这篇文章主要介绍String Task，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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.
代码如下：
`#include <stdio.h>
int main()
{
int A,B;
while (scanf("%d%d",&A,&B)!=EOF)
{

if(A+B%86==0)
printf(“yesn”);
else
printf(“non”);
}
}`因为第一次打ACM，格式不太了解
