【Uva 10082】 WERTYU

Description

A common typing error is to place the hands on the keyboard one row to the right of the correct position. So “Q” is typed as “W” and “J” is typed as “K” and so on. You are to decode a message typed in this manner.

Input

Input consists of several lines of text. Each line may contain digits, spaces, upper case letters (except Q, A, Z), or punctuation shown above [except back-quote (`)]. Keys labelled with words [Tab, BackSp,Control, etc.] are not represented in the input.

Output

You are to replace each letter or punction symbol by the one immediately to its left on the ‘QWERTY’keyboard shown above. Spaces in the input should be echoed in the output.

Sample Input

O S, GOMR YPFSU/

Sample Output

I AM FINE TODAY.

解题思路

可以先把键盘中的字符存成字符数组，根据输入的字符，再输出它左边的字符即可.

参考代码

#include <stdio.h>char s[] = "`1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";int main(){    int i,c;    while ((c = getchar()) != EOF){        for (i = 1;s[i] && s[i]!=c;i++);//找到当前输入的字符在数组中的位置        if (s[i])            putchar(s[i-1]);        else             putchar(c);    }    return 0;}
