#include "Dec2Bin.h"
#include<iostream>
using namespace std;
   
Dec2Bin::Dec2Bin(string decimal)
{
    Dec = decimal;
}
 
int Dec2Bin::GetBinary()
{
    return Bin;
}
 
void Dec2Bin::convert()
{
    Bin = 1;
    for(int i = 0; i < Dec.size(); i++)
    {
                Bin *= 10;
                Bin += Dec[i] - '0';
    }

{
    string Dec;
    int Bin;  
    public:
    void convert();
    Dec2Bin(std::string);
    int GetBinary();
};

using namespace std;
int main()
{
string s=("d43");
Dec2Bin conv(s);
conv.convert();
cout<<conv.GetBinary()<<endl;
return 0;
}

That means you haven't even tried to convert the decimal into binary. At least please show us the number with only 0 and 1.

You should definitely attempt your homework before asking for help.
Googling "How to convert numbers to binary" brought up loads of results.

    }
}

That is NOT the code to convert decimal to binary.

What answer is this? Is it even a binary number?
