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. If the allocation fails, it returns NULL.

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.
