Now, this particular structure is rather small compared to many used in C programs. To ... Consider the case described, i.e. we want a function that will accept as a parameter a · pointer to a structure and from within that function we want to access members of the · structure. For example we want to print out the name of the employee in our example

So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps. As you know, every variable is a memory location and every memory location has its address · defined which can be accessed using ampersand & operator, which denotes an address in · memory. Consider the following example...

integer variable. In this guide, we will discuss pointers in C programming with the help of examples.

Examples illustrate accessing values through pointers in arrays and demonstrate handling strings with pointers.View · Slides 27 - 31Advanced Pointer Concepts: Void and Function Pointers · Void pointers can reference any data type.
