HDU 2140 Michael Scofield's letter

http://acm.hdu.edu.cn/showproblem.php?pid=2140

Problem Description

I believe many people are the fans of prison break. How clever Michael is!! In order that the message won't be found by FBI easily, he usually send code letters to Sara by a paper crane. Hence, the paper crane is Michael in the heart of Sara. Now can you write a program to help Sara encode the letter from Michael easily?
The letter from Michael every time is a string of lowercase letters. You should encode letters as the rules below:
b is ' ', q is ',', t is '!', m is l, i is e, c is a, a is c, e is i, l is m. It is interesting. Are you found that it is just change michael to leahcim?

 

Input

The input will consist of several cases, one per line.
Each case is a letter from Michael, the letteres won't exceed 10000.

 

Output

For each case, output the encode letter one line.

 

Sample Input

pmicsibforgevibliqbscrct

ebmovibyout

 

Sample Output

please forgive me, sara!

i love you!

 

代码：

#include <bits/stdc++.h>
using namespace std;

const int maxn = 1e5 + 10;
char s[maxn];
char a[11]={'b', 'q', 't', 'm', 'i', 'c', 'a', 'e', 'l'};
char b[11]={' ',  ',', '!', 'l', 'e', 'a', 'c', 'i', 'm'};

int main() {
    while(~scanf("%s", s)) {
        int len = strlen(s);
        for(int i = 0; i < len; i ++) {
            if(s[i] == 'b')
                s[i] = ' ';
            else if(s[i] == 't')
                s[i] = '!';
            else if(s[i] == 'm')
                s[i] = 'l';
            else if(s[i] == 'i')
                s[i] = 'e';
            else if(s[i] == 'c')
                s[i] = 'a';
            else if(s[i] == 'a')
                s[i] = 'c';
            else if(s[i] == 'e')
                s[i] = 'i';
            else if(s[i] == 'l')
                s[i] = 'm';
            else if(s[i] == 'q')
                s[i] = ',';
        }

        printf("%s\n", s);
    }
    return 0;
}
