这个项目应该怎么去写，代码是怎样的

C代码如下：

#include <stdio.h>
//10进制转radius进制
void trans(int n,int radius,char buf[])
{
    int i = 0;
    int t,j;
    char ch;
    while(n)
    {
        t = n%radius;
        if(t >= 10)
            buf[i] = 'A' + t-10;
        else
            buf[i] = '0' + t;
        i++;
        n/=radius;
    }
    buf[i] = 0;
    
    //逆序
    for (j=0,t=i-1;j<t;j++,t--)
    {
        ch = buf[j];
        buf[j] = buf[t];
        buf[t] = ch;
    }
    
}

int main()
{
    int n;
    char buf[20]={0};
    scanf("%d",&n);
    trans(n,2,buf);
    printf("2进制：%s\n",buf);
    trans(n,5,buf);
    printf("5进制：%s\n",buf);
    trans(n,8,buf);
    printf("8进制：%s\n",buf);
    trans(n,16,buf);
    printf("16进制：%s\n",buf);
    return 0;
}

#include <iostream>
using namespace std;
void main()
{
 int n; //求的十进制数
 cout << "请输入一个十进制数" << endl;
 cin >> n;


 int saveData[1000]; //保存转换后的的位数；
 int count = 0;   //统计转换后有多少位数
 int radix =0 ; //转换的基数比如2表示二进制，8表示8进制...

 cout << "输入你需要转换的进制数" << endl;
 cin >> radix;

 int x;
 for (int i =0; n; ++i)
 {
  x = n % radix;
  n = n / radix;
  saveData[i] = x;

  ++count;
 }

 cout << "转换为" << radix << "进制：" ;
 for (int j = count -1; j >= 0; --j)
 {
  cout << saveData[j];
 }
 int wait;
 cin >> wait;

}
