1027 Colors in Mars (20 point(s))
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
题目大意:
输入三个十进制的数(0 ~ 168),输出转换为十三进制的数,前面加上一个 # 号
设计思路:
输入 0 ~ 168 的十进制,转换十三进制不会超过两位数
编译器:C (gcc)
#include <stdio.h>
int main(void)
{
char convert[]= "0123456789ABC";
int n;
int i;
for (i = 0; i < 3; i++) {
scanf("%d", &n);
if (i == 0)
printf("#");
printf("%c%c", convert[n / 13], convert[n % 13]);
}
return 0;
}
