將一個數轉換成n進位數

//將一個數轉換成n進位數//思想：建立一個table表來映射#include<iostream>using namespace std;int main(){        int num,n; //將 num 轉換成 n進位數        char table[32] =  {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V'};        char res[100];        cin>>num>>n;        int i = 0;        do {                res[i++] = table[num%n];                num = num/n;        } while(num != 0);        for(i -= 1; i >= 0; i--)                cout<<res[i];        return 0;}
