PAT甲级——A1027 Colors in Mars

People in Mars represent the colors in their computers in a similar way as the Earth people. That is, a color is represented by a 6-digit number, where the first 2 digits are for Red, the middle 2 digits for Green, and the last 2 digits for Blue. The only difference is that they use radix 13 (0-9 and A-C) instead of 16. Now given a color in three decimal numbers (each between 0 and 168), you are supposed to output their Mars RGB values.

Input Specification:

Each input file contains one test case which occupies a line containing the three decimal color values.

Output Specification:

For each test case you should output the Mars RGB value in the following format: first output #, then followed by a 6-digit number where all the English characters must be upper-cased. If a single color is only 1-digit long, you must print a 0 to its left.

Sample Input:

15 43 71

Sample Output:

#123456

只能说巨简单！

 #include <iostream>
 #include <string>
 using namespace std;
 int main()
 {
     int a[];
     string str = "0123456789ABC";
     cin >> a[] >> a[] >> a[];
     printf("#%c%c%c%c%c%c\n", str[a[] / ], str[a[] % ],
         str[a[] / ], str[a[] % ], str[a[] / ], str[a[] % ]);
     return ;
 }
