Question

Not able to understand whats happening in the below code

wchar_t wc;

wc =L'ab';

char ch = 'ab'; 

When i am debugging the above code , i found that a is stored in wc where as b is stored in ch .
I dont understand why a is not being stored inside the ch.

Answer 1

It’s compiler defined behavior:

On VS2012, I get 'a', 'b' output

on gcc 4.7.2, I get 'b', 'b' output and I get warning when I compile it:

warning: character constant too long for its type [enabled by default]
warning: multi-character character constant [-Wmultichar]
warning: overflow in implicit constant conversion [-Woverflow]
