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

If we overloaded std::begin() and std::end() for const char arrays to return one less than the size of the array, then the following code would output 4 instead of the expected 5:

#include 

int main()
{
    const char s[5] = {'h', 'e', 'l', 'l', 'o'};
    int i = 0;
    for (auto e : s)
        ++i;
    std::cout << "Number of elements: " << i << '\n';
}
