do while with character problem

[fukki]

Hello, i have the following code

char ans;
do
{
       cout<< "Do you want to continue (Y/N)?\n";
       cout<< "You must type a 'Y' or an 'N'.\n";
       cin >> ans;
}
while((ans !='Y')&&(ans !='N')&&(ans !='y')&&(ans !='n'));

and when i type more than one character, e.x wqe
i got output

Do you want to continue (Y/N)?
You must type a 'Y' or an 'N'.
Do you want to continue (Y/N)?
You must type a 'Y' or an 'N'.
Do you want to continue (Y/N)?
You must type a 'Y' or an 'N'.

Is it possible to just output only one time and not 3 ?

Thanks!

You can ignore all characters after the first using
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');

or read a string and take only its first character:

string str;
getline(cin,str);
if (str.empty())ans=0;
else ans=str[0];
