做法自然还是构建一个容器处理方便

#include<stdio.h>#include<string.h>int main(void){  char ch[1000], s[50] = "`1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";  int i, j, len, flag, count;  while(gets(ch))  {    len = strlen(ch);    for(i = 0; i < len; i++)    {      for(j = 0; j < strlen(s); j++)      {        if (ch[i] == s[j])        {            flag = 1;            count = j-1;            break;        }        if (ch[i] != s[j])        {            flag = 0;        }      }            printf("%c", flag?s[j-1]:ch[i]);    }    printf("\n");  }}

但是看到刘大之后顿时钦佩，简洁之道

#include<stdio.h>char s[] = "`1234567890-=QWERTYUIOP[]\\ASDFGHJKL;'ZXCVBNM,./";int main(void){  int i, c;  while((c = getchar()) != EOF)  {    for(i = 1; s[i] && s[i] != c; i++);      if (s[i]) putchar(s[i-1]);      else putchar(c);  }}
