c - Reasons for compilation error -

-

enter image description here

the hackerearth facebook page uploads mcqs these everyday! so, suppose can share image here. seems me compilation error! because of fact there statement post-increments char array a in for loop! last 2 statements::

&lt;p<<k }

are valid in way? < & > converted &gt; &lt; etc link says < gets converted &lt;! or compiler error?

was curious because couldn't trust myself compilation error closing bracket , &lt;p<<k; statement there in question!

the last 2 lines not supposed there. question differences between arrays , pointers. found answer: a array, not pointer, , can therefore not post-incremented.
