template<class BidIt>
bool operator>=(const sub_match<BidIt>& left,
const typename iterator_traits<BidIt>::value_type& right);
Parameters
BidIt
The iterator type.IOtraits
The string traits class.Alloc
The allocator class.left
The left object to compare.right
The right object to compare.
Remarks
Each template operator returns !(left < right).
Example

// compile with: /EHsc
#include <regex>
#include <iostream>
typedef std::tr1::cmatch::string_type Mystr;

std::cout << "sub == " << sub << std::endl;
std::cout << std::endl;
std::cout << "sub >= sub == " << std::boolalpha
