Printers are just another kind of variables, which can store address of another variable and can change value of that variable permanently. When we use pointer as parameters in functions then it's called Call by Reference. Asterisk (*) is used to define a pointer. You need to use adress of operator (&) to store address of another variable. For example: int x=10; int *ptr = &x; *ptr = 20; printf ("%d ",x); //output 20. printf ("%d ",*ptr); //also 20

Martin Taylor really?!!! What do those two books say about pointers? I think a maximum of ten pages is enough to fully explain them.

Pointer is just a variable like other variables but it is used to store address of other variables. So, you will be able to access that variable using it's address
