If you do

printf("*p1 %d ",*p1);
printf("*p2 %d ",*p2);

after the code (refer to my previous comment) then both of them will contain the same value i.e. 3.

CONSIDER ANY INSTANCE OF PROGRAM AND P IS POINTER

{

STMT1;

STATEMENT 2;

..........................

.......................

.....................

++*P;  // THIS WILL TAKE VALUE POINTED BY P AND THEN INCREMENT THE VALUE

(*P)++; // THIS WILL TAKE VALUE AND THEN INCREMENT THE VALUE

*P++; // THIS WILL TAKE THE VALUE AND THEN INCREMENT THE POINTER

 

}                 //IS IT RIGHT??

@eyeamgj

yes you are right !

Answer 1

++*p  means first we will access the value pointed by p and then we will increment that value(as it is preincrement so incremented value will be printed )

and (*p)++ first we will acesss the value pointed by p and print it then we will increment the value (as it is post increment)
