UVa 10222 Decode the Mad man

想法：
　　先建立一個鍵盤keyboard，然後輸入一個字元c之後就找在keyboard裡的index，並輸出keyboard[i-2]。

	#include <cstdio>
	#include <cctype>
	using namespace std;
	const char keyboard[] = "`1234567890-=qwertyuiop[]\\asdfghjkl;'zxcvbnm,./";
	int main()
	{
	char c;
	while (scanf("%c",&c) != EOF){
	c = tolower(c); //換成小寫字母
	if (isspace(c)) printf("%c",c); //如果為' '或'\n'直接輸出
	else{
	for (int i=0; keyboard[i]; ++i)
	if (c == keyboard[i]){
	printf("%c",keyboard[i-2]);
	break;
	}
	}
	}
	return 0;
	}
