C provides a mechanism for allocating memory during program execution, known as dynamic memory allocation. Unlike static memory allocation where variables are assigned space at compile time, dynamic allocation allows you to request memory at runtime based on your program's needs. This flexibility is crucial for tasks like processing data of unknown size beforehand or creating and destroying data structures on the fly.
