DMA stands for Dynamic Memory Allocation, DMA allows us to allocate memory at run time. Generally variable allocates the memory at compile time, for example int a; here, a will allocate memory at compile time.

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.

Pointers provide necessary support for C++'s powerful dynamic memory allocation system. Dynamic Allocation is the means by which a program can obtain memory during runtime. The global and local variables are allocated memory during compile-time. However, you cannot add any global or local variables during runtime.

Sometimes the size of the array you declared may be insufficient. To solve this issue, you can allocate memory manually during run-time. This is known as dynamic memory allocation in C programming. To allocate memory dynamically, library functions are malloc (), calloc (), realloc () and free () are used.
https://en.wikipedia.org/wiki/C_dynamic_memory_allocation
The C dynamic memory allocation functions are defined in stdlib.h header (cstdlib header in C++). malloc() takes a single argument (the amount of memory to allocate in bytes), while calloc() needs two arguments (the number of variables to allocate in memory, and the size in bytes of a single variable).
