This question In comparison to other simpler techniques such as dynamic allocation, the buddy memory system has little external fragmentation, and allows for compaction of memory with little overhead. The buddy method of freeing memory is fast, with the maximal number of compactions required equal to log 2 (highest order). Dynamic memory allocation in C We can dynamically allocate and de-allocate memory to variables in C language. Different functions for dynamic memory allocation/de-allocation are: malloc() free() 1. malloc() function malloc() is a predefined function of C language that can dynamically allocate memory to variables.

Allocating memory dynamically allows you to create pointers at runtime that are just large enough to hold the amount of data&n Dynamic memory Allocation in C. Suppose you want to put a toy in a box, but you only have an approximate idea of its size. For that, you  Dynamic memory allocation¶. The use of arrays is a problem when we do not know the size of the needed array in advance. The program will not run if we don' t allocate enough memory and it wastes space if we allocate too much memory.
