The sample code below illustrates how to use the string::getline
STL function in Visual C++.
Required Header:
<string>
template<class _E, class _TYPE, class _A> inline
basic_istream<_E, _TYPE>& getline( basic_istream<_E, _TYPE>& Istream,
basic_string<_E, _TYPE, _A>& Xstring,
const _E _D=_TYPE::newline());
Note: The class/parameter names in the prototype do not match the version in the header file. Some have been modified to improve readability.
Description:
The getline function creates a string containing all of the characters from the input stream until one of the following situations occurs: - End of file. - The delimiter is encountered. - is.max_str() elements have been extracted.
Sample Code:

using namespace std ;
void main()
{
string s1;
cout << "Enter a sentence (use <space> as the delimiter):";
getline(cin,s1, ' ');
cout << "You entered: " << s1;
}
Program Output is:
Enter a sentence (use <space> as the delimiter): A_space_at_the_end.
You entered: A_space_at_the_end.
