#include <boost/algorithm/string.hpp>
// Or, for fewer header dependencies:
//#include <boost/algorithm/string/predicate.hpp>

std::string str2 = "HELLO, WORLD!";

if (boost::iequals(str1, str2))
{
    // Strings are identical
}

C++ compare strings

if ((str1.compare(str2) == 0) || (str1 == str2))
  // they are EQUAL

// str1.compare(str2):
// < 0	Either the value of the first character that does not match is lower in the compared string, or all compared characters match but the compared string is shorter.
// > 0	Either the value of the first character that does not match is greater in the compared string, or all compared characters match but the compared string is longer.
