string::operator>>
Illustrates how to use the string::operator>> Standard Template Library (STL) function in Visual C++.
template<class E, class TYPE, class A> inline
basic_istream<E, TYPE>&
operator>>(basic_istream<E, TYPE>& InStream,
basic_string<E, TYPE, A>& String);
Remarks
Note
The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.
The operator>> is used to populate a string with the contents of an input stream.

This operator copies data from an input source to a variable. If the input is not verified, this could potentially lead to a buffer overrun. For more information, see Avoiding Buffer Overruns. |
