cz when u do char p[]="hello" compiler automatically allocates enough
memory(6 charc here) and puts your string there......
but whn u do char*a="hello" then its complr dependent where d string will be
stored....some compiler stores it in a special location in data segmnt whch
is (read only )so modifying the string is error....other compiler stores it
in write allowed memory so u can alter d string there.......
