Pointers in c with examples programs

String literals are arrays containing null-terminated character sequences. This means that void pointers have great flexibility as it can point to any data type. There is payoff for this flexibility. These pointers cannot be directly dereferenced. They have to be first transformed into some other pointer type that points to a concrete data type before being dereferenced. Skip to content.

Let's take a working example. Note: You will probably get a different address when you run the above code. Pointers pointer variables are special variables that are used to store addresses rather than values.

Here, 5 is assigned to the c variable. And, the address of c is assigned to the pc pointer. For example:. Here, the address of c is assigned to the pc pointer. It operates on a pointer and gives the value stored in that pointer. Then, we changed the value of c to 1. Since pc and the address of c is the same, c will be equal to 1. Now you know what pointers are, you will learn how pointers are related to arrays in the next tutorial.
