1. Pointer for a variable Pointers, which are the addresses of variables. For example in this code snippet: inta =54; 54 is the value of the variable, in other words, it is the value that is stored in the location reserved for the variable called 'a'.Now, let's ask ourselves, wher...
To get the value of the thing pointed by the pointers, we use the*operator. For example: int* pc, c; c =5; pc = &c;printf("%d", *pc);// Output: 5 Here, the address ofcis assigned to thepcpointer. To get the value stored in that address, we used*pc. ...
Manipulating Pointers In the preceding code snippet we saw, ptr was pointing to x i.e. ptr contained the address of the location in which x is stored. The data item represented by x can be accessed by using the unary operator *, which is also termed as the indirection operator can be ...

Why you have done too complex in swapping with pointers. Remember & is used for reference. I think that you know about call by value and call by reference. If you give & in any function it takes from the main function as the call by reference and if you dont use & it takes call ...
