How to Ingore the input of std::cin??

[yw]

Hi,
When I use std::cin and std::cout to input some data, how can I ingore the
cin by using the Enter key?
For example:

string sname;
cout<<"Please input your name:"<<endl;
cin>>sname;

If I don't wan't to input anything, just press enter key to ingnore the cin
step, and jump the cin step when the cin requires to input something?

Thanks ,any help will be appreciate.

Not sure I understand.

For example:

string sname;
cout<<"Please input your name:"<<endl;
cin>>sname;

If I don't wan't to input anything, just press enter key to ingnore the
cin
step, and jump the cin step when the cin requires to input something?

If you just press the enter key, what happens? Does it still sit there
waiting or does the 'sname' come out empty?
