Re: what is the difference between these initializations? Char a[]=”string”; Char *p=”literal”; Does *p++ increment p, or what it points to?

Answer
# 1

surely there is some difference.....

here 'a' is represented as array in which string gets stored
in consecutive locations......

p is a pointer variable where string is initilized... so in
p the base address of "literal " will get stored...... 

*p++ increments 'p' , but pertaining to some conditions.....
++ has more precedence than * , so first it will increment
the address and correspondingly it will show the value as *
precedes..... so after the increment the p points to 'i'...



thank u

Answer
# 2

I am totally satisfied with your above explanation except
last one. 
i.e.  Char *p="literal";
So, i want to mention yes this will work.
Explanation: *p++. 
Here we have post increment. 
Postfix increment/decrement have high precedence, but the
actual increment or decrement of the operand is delayed (to
be accomplished sometime before the statement completes
execution).
value of printf("\nstr=%c\n",*p++) will be 'l', but before
complete execution of this statement p will point to string
"iteral" as p got incremented.
