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

// std_tr1__regex__operator_ge.cpp 
// compile with: /EHsc 
#include <regex> 
#include <iostream> 
 
typedef std::tr1std::cmatch::string_type Mystr; 
int main() 
    { 
    std::regex rx("c(a*)|(b)"); 
    std::cmatch mr; 
 
    std::regex_search("xcaaay", mr, rx); 
 
    std::csub_match sub = mr[1]; 
    std::cout << "sub == " << sub << std::endl; 
    std::cout << std::endl; 
 
    std::cout << "sub >= sub == " << std::boolalpha 
        << (sub >= sub) << std::endl; 
 
    std::cout << "string(\"aab\") >= sub == " << std::boolalpha 
        << (Mystr("aab") >= sub) << std::endl; 
    std::cout << "sub >= string(\"aab\") == " << std::boolalpha 
        << (sub >= Mystr("aab")) << std::endl; 
 
    std::cout << "\"aab\" >= sub == " << std::boolalpha 
        << ("aab" >= sub) << std::endl; 
    std::cout << "sub >= \"aab\" == " << std::boolalpha 
        << (sub >= "aab") << std::endl; 
 
    std::cout << "'a' >= sub == " << std::boolalpha 
        << ('a' >= sub) << std::endl; 
    std::cout << "sub >= 'a' == " << std::boolalpha 
        << (sub >= 'a') << std::endl; 
 
    return (0); 
    } 
 

sub == aaa

sub >= sub == true
string("aab") >= sub == true
sub >= string("aab") == false
"aab" >= sub == true
sub >= "aab" == false
'a' >= sub == false
sub >= 'a' == true
