all these *chars acts as an array the ' *a ' initially indicates/ points the first charactr of the string and as the *a gets incremented the memory address is increased. as like in arrays. also these are defined in chars so output is also a char not a string so 'n' is the right answer

the output is "n" because you assigned "a" from second character(++a) to end to "b" and you want print a character in the index "3" from this "oding", that is 'n'
