C dynamic memory allocation refers to performing manual memory management for dynamic memory allocation in the C programming language via a group of functions in the C standard library, namely malloc, realloc, calloc and free .
Read moreHow dynamically allocate memory for 2d array in C?
int row = 2, col = 3; int *arr = (int *)malloc(row * col * sizeof(int)); int i, j; for (i = 0; i < row; i++) for (j = 0; j < col; j++) *(arr + i*col + j) = i + j; Then the values of the 2-D array are displayed. Finally the dynamically allocated memory is freed using free. The code snippet that shows this is as follows.

Read moreHow do you dynamically allocate memory for an array?
dynamically allocated arrays To dynamically allocate space, use calls to malloc passing in the total number of bytes to allocate (always use the sizeof to get the size of a specific type). A single call to malloc allocates a contiguous chunk of heap space of the passed size.
Read moreHow is dynamic memory allocation done in C?
In C, dynamic memory is allocated from the heap using some standard library functions . The two key dynamic memory functions are malloc() and free(). The malloc() function takes a single parameter, which is the size of the requested memory area in bytes. It returns a pointer to the allocated memory.
