c++ issue(urgent)

Rone is float.

cout << "Enter R1 of Delta Network" <<"\n";
cin >> Rone;
if(Rone>0)
{
}
else
{
cout<< "R1 does not accept zero ,negative and character values";
cout << "Enter R1 of Delta Network" <<"\n";
cin >> Rone;
}


My mistake if i press any character it's going into the loop.It's not stopping.How to solve this problem.

Thanks and regards,
Mala

What loop?
Please give us more details!

Characters have a numeric value that is > 0.

For instance:
'A' == 0x41
'B' == 0x42

loop means
again and again The below message are displaying.
Messages("R1 does not accept zero ,negative and character values ,Enter R1 of Delta Network")

It's going to line1 and line2 .It's not going to line no 3.If it's goes only i can enter the input again.

line1,
cout<< "R1 does not accept zero ,negative and character values";
line2,
cout << "Enter R1 of Delta Network" <<"\n";
line3,
cin >> Rone

How to stop this message and give input to cin >>Rone

Thanks and regards,
Mala

Can you post your loop code snippet, the one which uses while/for or something similar to loop your messages around...(:)*)
