Dereferencing
Dereferencing is a programming concept that involves accessing the value stored at a specific memory address. In languages like C or C++, pointers are used to hold memory addresses, and dereferencing allows you to retrieve or manipulate the data at that address. This is done using the dereference operator, typically represented by an asterisk (*).
When you dereference a pointer, you can read or modify the value it points to. For example, if you have a pointer that points to an integer variable, dereferencing it gives you access to that integer's value. Proper dereferencing is crucial for effective memory management and avoiding errors like segmentation faults.
