浙江大学PAT_甲级_1027. Colors in Mars (20)

题目链接:点击打开链接

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

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

Output

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 the left.

Sample Input
15 43 71
Sample Output
#123456

The only difference is that they use radix 13 (0-9 and A-C) instead of 16. 

唯一的区别是,他们使用的,而不是16基数13(0-9和AC)。

输入的数字要转换为13进制。

C++程序:

#include<iostream>
#include<string>
using namespace std;
void transform(int num)
{
	char c[3] = { 'A','B','C' };
	if (num / 13 >= 10)// num / 13商数
	{
		cout << c[num / 13 - 10];
	}
	else
	{
		cout << num / 13;
	}
	if (num % 13 >= 10)// num % 13 余数
	{
		cout << c[num % 13 - 10];
	}
	else
	{
		cout << num % 13;
	}
}
int main()
{
	int a, b, c;
	cin >> a >> b >> c;
	cout << '#';
	transform(a);
	transform(b);
	transform(c);
	//system("pause");
	return 0;
}
