Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do

pointers are not a necessary tool. However, I'm going to cover them now rather than later in this series because they are closely related to arrays, which we discussed in theprevious article. Also, pointers help to reinforce our understanding of the relationship between code and hardware. ...

1. Pointers enable us to use call by reference mechanism. This enables changes to the formal parameters within a function to be reflected in arguments in the function call. Thus, the modified values are passed back to the calling function. ...

/* The contents of memory location are changed */ temp=*x; *x=*y; *y=temp; } Output: Before function call: a=5 b=7 After function call: a=7 b=5 Steps involved for using pointers in a function are Pass address of the variable (Using the ampersand (&) or direct pointer variable...
I have found that often the main reason beginners have a problem with pointers is that they have a weak or minimal feeling for variables, (as they are used in C). Thus we start with a discussion of C variables in general. A variable in a program is something with a name, the value...
