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
#include<iostream>
using namespace std;
int main(){
int a,b,c;
int len1=0,len2=0,len3=0;
int a1[10],b1[10],c1[10];
while(scanf("%d%d%d",&a,&b,&c)!=EOF){
do{
a1[len1++]=a%13;
a=a/13;
}while(a!=0);
do{
b1[len2++]=b%13;
b=b/13;
}while(b!=0);
do{
c1[len3++]=c%13;
c=c/13;
}while(c!=0);
printf("#");
for(int i=len1-1;i>=0;i--){
if(a1[i]<10){
printf("%d",a1[i]);
}else{
printf("%c",a1[i]-'A'+10);
}
}
for(int i=len1-1;i>=0;i--){
if(b1[i]<10){
printf("%d",b1[i]);
}else{
printf("%c",b1[i]-'A'+10);

参考答案
#include <cstdio>
using namespace std;
int main() {
char c[14] = {
"0123456789ABC"};
printf("#");
for(int i = 0; i < 3; i++) {
int num;
scanf("%d", &num);
printf("%c%c", c[num/13], c[num%13]);
}
return 0;
