Answer 2

Rishi see here
int number =1; //normal integer variable
int *ptr ; //ptr is pointer variable
ptr=&number; //ptr store's the address of variable number
// pointer points to an address of a variable
*ptr=*&number;
//by dereferencing ptr gives the value stored at address which was pointing

//so *ptr =1 ;
