Answer 2

Answer:

think many of the compilers will give an error or may your program will be crash bcz first of all you must initilize a pointer variable ,which points a valid memory location.

******here,char *p=0(i.e,p is a null pointer)null pointer means a pointer variable doesn’t contain of any valid memory location of memory block.
