To allocate memory dynamically, library functions are malloc() , calloc() , realloc() and free() are used. These functions are defined in the <stdlib. h> header file.
Read moreWhat is dynamic memory allocation in C programming?
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 moreWhat is dynamically memory allocation?
Dynamic memory allocation is a process that allows us to do exactly what we’re looking to do above, to allocate memory while our program is running, as opposed to telling the computer exactly how much we’ll need (and for what) ahead of time.
