I am a little bit of confusing how to make a correct allocation. Can anyone make it with a explaination? I would rate your solution. Thanks!

typedef struct { int val; double priority; } HeapElement; // Array representation of the heap, with some metadata typedef struct { int numItems; // Number of items currently in the heap int maxSize; // Total (maximum) size of the heap HeapElement *arr; int *indices; } MinHeap; // The actual array representing the minHeap // indices [key] = index of key in `arr, or -1 /** * Allocate a new min heap of the given size. * * * TODO: Allocate memory for the MinHeap' object, and the 2 arrays inside it. ^numItems' should initially be set to 0, and all the indices should be set to -1 to start with (since we don't have anything in the heap). */ MinHeap *newMinHeap(int size) { *
