Pat(Advanced Level)Practice--1027(Colors in Mars)

Pat1027代码

题目描述：

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

AC代码：

#include<cstdio>using namespace std;void Transform(int n){char temp[3];int i=1;temp[2]='\0';while(i>=0){int t=n%13;n=n/13;if(t>=10)temp[i]=t-10+'A';elsetemp[i]=t+'0';i--;}printf("%s",temp);}int main(int argc,char *argv[]){int i;int A[3];for(i=0;i<3;i++)scanf("%d",&A[i]);printf("#");for(i=0;i<3;i++)Transform(A[i]);printf("\n");return 0;}

其实就是10进制与N进制的转换，没什么好说的。。。
