Segmentation fault (core dumped) in a simple C code

Question

I am new in C. I am referring to the book \"The C Programming Language\" by Brian W Kernighian and Dennis Ritchie. There is a code for pointer increment and assignment give

Answer 1

When ever we say *s = "hello" , s is pointing to an address which is present in text segment("hello" goes into text segment). So obviously changing the value of text segment results in SEGV termination.

And for s[] = "hello" if we do *s++, we are incrementing (modifying) the base address so we got "lvalue required as increment operand" error.
