| Malloc is used to allocate memory for specific purposes. For breakout, since we'll know how many bricks are going into our brick field, we'll use an array. An array is always the same size, which means the amount of memory used for the array will remain constant. Malloc is perfect for this scenario. | Malloc is used to allocate memory for specific purposes. For breakout, since we'll know how many bricks are going into our brick field, we'll use an array.

| + | When the malloc() function is called, it sends a request to the heap in the form of a memory block (heap is memory allocated for each program). The heap's available memory must be at least equivalent to the memory block size. In this case, it will assign the malloc() that memory size function against its request. If the heap has no memory, null value is returned. The memory block is cleared using the free() function to free up the memory for other program instructions. | ||
