Static Allocation
Static allocation is a memory management technique where memory for variables is allocated at compile time and persists for the entire duration of a program's execution. It is commonly used for global variables, static variables, and constants, with memory size determined before runtime. This approach contrasts with dynamic allocation, where memory is allocated and deallocated during program execution.
Developers should use static allocation when they need predictable memory usage, such as for fixed-size data structures, constants, or variables that must persist throughout the program's lifecycle, like configuration settings. It is essential in embedded systems, real-time applications, and performance-critical code where memory overhead and runtime allocation delays must be minimized.
