Name

operator== function template — Compares strings for equality

Synopsis

template<class charT, class traits, class Allocator>
  bool operator==(
    const basic_string<charT,traits,Allocator>& a,
    const basic_string<charT,traits,Allocator>& b);
// bool operator==(const string& a, const string& b);
template<class charT, class traits, class Allocator>
  bool operator==(const charT* a, const basic_string<charT,traits,Allocator>& b);
// bool operator==(const char* a, const string& b);
template<class charT, class traits, class Allocator>
  bool operator==(const basic_string<charT,traits,Allocator>& a, const charT* b);
// bool operator==(const string& a, conat char* b);

The == operator compares two strings for equality or compares a string and a null-terminated character array. It returns a.compare(b) == 0, converting a or b from a character array to a string, as needed.
