@Sriram.

Because there is %c format specifier in the printf function.

The void pointer can't accept any arithmetic operation then how it is possible?

Sriram said:   9 years ago
In the 9th line it is integer type casting how 'A' is displayed.

In step 2.

printf("%c", *(int*)vp);
Why doesn't it print 65 in place of 'A'?

(since it is typecast to int type and j also holds an integer).
