String plus Char - what is happening?

Question

I'm just curious about what is going on when trying to add a char to a string.

Initially, I thought it would work like a concatenation but it didn't:

cout<<"ab"+'a'<<endl;
cout<<""+'a'<<endl;

Prints

However,

cout<<"bla"<<endl;
cout<<"ab"+'a'<<endl;
cout<<""+'a'<<endl;

Prints

String literals are char const[N] (decays to char const *), and char is a small range integer type. You're doing pointer arithmetic.
