1027 Colors in Mars (20分)

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


10进制转13进制，用除法，且结果最多两位。
所以可以使用一个字符串来存储每一位的结果
将10进制的每一位用13进制来表示，然后去字符串中找对应的结果并输出

#include<iostream>
using namespace std;
int main()
{
    string a ={"0123456789ABC"};//用一个字符串来存储要输出的结果
    int num1,num2,num3;
    while(scanf("%d %d %d",&num1,&num2,&num3))
    {
        printf("#");
        printf("%c%c%c%c%c%c",a[num1/13],a[num1%13],a[num2/13],a[num2%13],a[num3/13],a[num3%13]);
    }

    return 0;
}
