这个 C++ 程序有问题Decimal to Bin、Oct 和 Hex 转换器

问题描述

我想要做的是，创建一个程序，将十进制值转换为其他数字系统（二进制、八进制和十六进制-十进制）并显示原始十进制值以及转换后的值。

它在第一次运行时运行良好，但是当外部 for 循环再次运行程序时，内部 for 循环打印的先前值也会在下次运行输出后立即打印。有什么建议吗？

尝试运行它，并亲自查看... 源代码：-

#include <iostream>
using namespace std;
int main()
{
        cout << "This program will help in Decimal to other radix conversion :-"  << endl;
        const int i = 10;
        //Declaring array to store remainder values...
        int RemArray [i] = {0};
        //Declaring variable to use it as index of RemArray[]...
        short int R=0;
        char Exit = '\0';
    //To iterate the whole program...
        for (;;)
        {
                cout << "Enter Decimal digit: ";
                long long int Decimal = 0;
                cin >> Decimal;
                long long int TempDecimal = Decimal;
                cout << "Enter Desired Radix: ";
                int Radix = 0;
                cin >> Radix;
                long long int Quotient = 1;
                long long int Remainder = 0;
