basic_istream::peek
Returns the next character to be read.
int_type peek( );
Return Value
The next character that will be read.
Remarks
The unformatted input function extracts an element, if possible, as if by returning rdbuf ->sgetc. Otherwise, it returns traits_type::eof.
Example
// basic_istream_peek.cpp
// compile with: /EHsc
#include <iostream>
using namespace std;
int main( )
{
char c[10], c2;
cout << "Type 'abcde': ";
c2 = cin.peek( );
cin.getline( &c[0], 9 );
cout << c2 << " " << c << endl;
}
abcde
