C++ class error, it does not make sense to me at all!?

The code is below... When I convert to letter then number the binary is right. When I convert the number then letter the binary messes up. Help me.





class menu


{


public:


void convert (int input);


int getValue (int input);


};








int a[8],k=1,i ;


void menu::convert(int input)


{





int d = input;


i = 0;


while (d!=0)


{


a[i]=d % 2;


d/=2;


i++;


}


cout %26lt;%26lt; "The binary code of the given number is :";


for(i=7;i%26gt;=0;i--)


cout %26lt;%26lt; a[i] ;


cout %26lt;%26lt; endl;


}


int menu::getValue(int i)


{


char ans;


int ans2;


cout %26lt;%26lt; "What letter/number?\n%26gt;%26gt;";


if (i == 2){


cin %26gt;%26gt; ans;


ans2 = int (ans);}


else{


cin %26gt;%26gt; ans2;}


return ans2;


}


int main()


{


for (;;)


{


menu user ;


int c =0, d =0;


cin %26gt;%26gt; c;


if (c %26lt;= 2)


{ d = user.getValue(c);


user.convert(d); }


else{


break;}


}


system("pause");


return 0;


}

Your convert() function has few bugs.
