WebApr 12, 2024 · Dynamic memory allocation in C is a powerful feature that allows programmers to allocate memory dynamically during program execution. This dynamic allocation of memory makes it possible to optimize memory usage in a program and reduce the risk of memory leaks. WebUnlike our data types which specify a size, allocation in the heap can vary with each call. The heap is a space of dynamic memory that is reserved in the data segment. The heap is useful because it allows us to dynamically change the size of allocated data. Unlike other subsegments, static allocation reserves a set number of bytes.

WebThe realloc () function modifies the allocated memory size to a new size by the malloc () and calloc () functions. If enough space doesn't exist in the current block's memory to expand, a new block is allocated for the total size of the reallocation, then copies the existing data to the new block and frees the old block. WebIn this type of allocation, system memory is managed at runtime. Dynamic memory management in C programming language is performed using the malloc(), calloc(), realloc(), and free() functions. These four functions are defined in the C standard library header file. It uses the heap space of the system memory.
