Ace Test Series: Programming & DS - Array

Question

According to me Option D.

Because it should be an error because *("INDIA" + 2 ) = 'D' and we are doing 'D' = 'I' which is not valid so Error ???

But answer is C

Comments

printf("%c",*("INDIA"+2)='I'); // 'I'

 printf("%s",*("INDIA"+2)='I'); // segementation fault

"INDIA" represent a base address of string constant assume address is 1000.

now by doing *("INDIA"+2)='I' you are trying to modify string constant which is not allowed, Hence segmentation fault.

Answer 1

Attempting to write on Read-only location is a segmentation fault but not the error...
