Thread: Adding!

Hello,

I'm learning C++ and Dot Net and I hope this is the right forum. I'm very new to this game and I see to be having a little problem and was wondering if someone could shed some time.

The code below basicalyl asks a few questions (more will be added) and multiples the answer by the rate. What I want to do at the end is to add up all the results. So for example, TMB and TGB would be 5 each, so the total would be 10. But when I do it, it doesn't give me the right #. If TMB is 1.25 and TGB is 1.25, the answer should be 2.50, instead it reads out as 2. The error tells me that
warning C4244: '=' : conversion from 'double' to 'int', possible loss of data

I'm so lost on this part and if anyone could shed some light, i would be deeply appreciative.

Thanks

Code:

void selectMenu(int option)
{
	int mb=0;
	double tmb=0.0;
	int gb=0;
	double tgb=0.0;
	int sum=0;
	
		switch (option)
	{
	default:
	     Console::WriteLine("Error");
	case 1:
		Console::WriteLine("Megabytes?");
		mb=Convert::ToInt32(Console::ReadLine());
        tmb=mb*0.25;
		Console::WriteLine("{0}", Convert::ToString(tmb));
		Console::WriteLine("Gigabytes?");
		gb=Convert::ToInt32(Console::ReadLine());
        tgb=gb*0.25;
		Console::WriteLine("{0}", Convert::ToString(tgb));
		sum=tmb+tmb;
		Console::WriteLine("{0}", Convert::ToString(sum));
		
		break;
	case 2:
		Console::WriteLine("This is option 2");
		break;
	case 3:
		Console::WriteLine("This is option 3");
		break;
	}

}

The sum should be a double and not a int

I am a idiot! Sorry for bothering you and I appreciate it!

Thanks
