Storing a string in an array of chars without the null character

Question

I\'m reading the C++ Primer Plus by Stephen Prata. He gives this example:

char dog[8] = { \'b\', \'e\', \'a\', \'u\', \'x\', \' \', \'I\', \'I\'}; // not a s         


        

Answer 1

Its an undefined behaviour, you cannot say what can happen.

Try on some other system you may get different output.

The answer to your question is that it is an Undefined Behaviour and its output cannot be explained.

In addition to above explanantion, in your particular case, you have declared array globally. Therefore in your second example a \0 is appended in the fourth byte of four-byte boundary as explained by Peter Raynham.
