Inconsistency between std::string and string literals

Question

I have discovered a disturbing inconsistency between std::string and string literals in C++0x:

#include 
#include          


        

Answer 1

The inconsistency can be resolved using another tool in C++0x's toolbox: user-defined literals. Using an appropriately-defined user-defined literal:

std::string operator""s(const char* p, size_t n)
{
    return string(p, n);
}

We'll be able to write:

int i = 0;     
for (auto e : "hello"s)         
    ++i;     
std::cout << "Number of elements: " << i << '\n';

Which now outputs the expected number:

Number of elements: 5

With these new std::string literals, there is arguably no more reason to use C-style string literals, ever.
