An attempt to access a segment of memory not allocated to your program will generate a "segmentation fault", and represents an illegal operation on most systems.

How to do it...

Let's look at an example code that allocates a pointer variable i, then assigns memory to it using malloc(). We allocate a single integer behind an int* pointer. After allocation, we store a value inside int, using the dereferencing operator *:
