(Exp):
Since a void pointer is used it can be type casted to any other type
pointer.
vp = &ch stores address of char ch and the next statement prints
the value
stored in vp after type casting it to the proper data type pointer.
the output
is 'g'. Similarly the output from second printf is '20'. The third
printf
statement type casts it to print the string from the 4th value hence
the
output is 'fy'.
