A synchronization primitive used to control access to a shared resource by multiple processes or threads, allowing only a specified number to access it concurrently.

"The semaphore prevented multiple threads from accessing the critical section simultaneously."

The operation of accessing the data referred to by a pointer or reference.

"Dereferencing a null pointer in C or C++ results in undefined behavior, often leading to a program crash."

In programming, the process of breaking down a complex problem or function into smaller, more manageable parts, often to improve readability or reusability.

"Refactoring code by factoring out common functionality into separate functions can make the code cleaner and less prone to errors."

A linear collection of data elements, whose order is not given by their physical placement in memory.

"In a linked list, each element points to the next, making it a dynamic data structure that allows efficient insertions and deletions."

A data type used in programming to represent real numbers with fractional parts, using a point to separate the integer and fraction parts.

"Float variables are used in calculations that require precision, such as scientific computations and graphics programming."
