Diving into dynamic memory allocation

Report a typo

In operating systems, memory management takes care of several important tasks. Here is a C code snippet demonstrating a malloc function, which is often used for dynamic memory allocation. Can you identify the primary role of this function in the context of memory management?


#include 
int main() {
   int *ptr;
   ptr = (int*) malloc(15 * sizeof(int));
   if(ptr == NULL) {
      printf("Memory not allocated.\n");
      exit(0);
   }
}

Select one option from the list

It resizes the allocated memory by realloc function.

It allocates a specified amount of memory during runtime.

It completely clears the memory space, resetting it to a default state.

It evenly distributes memory across all running processes.

It frees up memory space after it's no longer needed.
