C Programming - Pointers - Discussion

Thanks nilesh.

Really fantastic explanation by nilesh good job.

Hey really very accurate answer.

ch=74 which is the ASCII value of J
j=65 which is the ASCII value of A
vp a void pointer contains the address of ch so it can be type casted to any type of pointer.
printf("%c", *(char*)vp);
(char*)vp type castes void type vp to char type and prints the value pointed by vp which is J.
vp=&j;
printf("%c", *(int*)vp);
Now vp contains the address of j.
*(int*)vp it type castes void type pointer vp to int type and prints the value pointed by vp which is A
vp=cp;
printf("%s", (char*)vp+2);
Now vp contains the value of cp. pointer vp is incremented by 2.so now it points to the letter C of JACK and prints the string CK.

So finally JACK is printed.

Thanks Nilesh, nice explanation.

Thanks Nilesh. Well explained.

q = (int**)&p;
Here void ptr is casted into integer ptr.

this was d explantion given for typecasting in 1 of the discussion...

*(char*)vp-dis is also typecasting.. but both differs..

For @Lucky:

ch is a character variable. From the character set, we can assign any kind of values to the character variable. The character set consists of floating point no. s, integers, characters, special characters etc. which when given charater datatype behave as character.

Thank you very much Nilesh.

Thank you very much NILESH.
