     10082 WERTYU


    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.

     

     1 #include<stdio.h> 
     2 /*使用判断语句太过繁琐,使用常量数组*/
     3 char s[] = "`1234567890-=QWERTYUIOP[]\ASDFGHJKL;'ZXCVBNM,./";
     4 int main()
     5 {
     6     int i,c;
     7     while((c = getchar()) != EOF )
     8     {
     9         for(i=1;s[i] && s[i]!=c;i++);//找错位之后的字符在常量表中的位置 
    10         if(s[i]) putchar(s[i-1]);//如果找到输出正确的字符 
    11         else putchar(c);
    12     }
    13     return 0;
    14 }

    定义常量数组无需指明大小,编译器可以完成计算。
