This document discusses dynamic memory allocation in C using malloc(), calloc(), and realloc(). Malloc() allocates a block of memory of the specified size. Calloc() allocates memory for an array and initializes it to zero. Realloc() changes the size of the memory block pointed to by an already allocated pointer.
