生成代码: 十进制与任意进制转换

好的，请稍等，让我为您生成一段代码：

#include <iostream>
#include <string>
using namespace std;
 
string convertToBase(int num, int base) {
    string digits = "0123456789ABCDEF";
    string result = "";
    while (num > 0) {
        int digit = num % base;
        result = digits[digit] + result;
        num /= base;
    }
    return result;
}
 
int convertFromBase(string num, int base) {
    int result = 0;
    for (int i = 0; i < num.size(); i++) {
        result = result * base + digits.find(num[i]);
    }
    return result;
}
 
int main() {
    int num = 12345;
    int base = 16;
    cout << num << " in base 10 is " << convertToBase(num, base) 
         << " in base " << base << endl;
 
    string str = "2AF3";
    base = 16;
    cout << str << " in base " << base << " is " << convertFromBase(str, base) 
         << " in base 10" << endl;
 
    return 0;
}

这段程序可以实现将一个十进制数转换为任意进制数，以及将任意进制数转换为十进制数。您可以根据需要修改代码中的变量值。希望这可以帮到您！
