Implement the functions in C (use malloc to allocate in heap) struct book { char bookTitle[50]; char bookAuthor[50]; }; void readBook(struct book* ); void printBook(struct book*);

Complete the code. The question is in the picture #include <iostream> using namespace std; class Queue { int size; int* queue; public: Queue() { size = 0; queue = new int[100]; } void add(int data) { queue[size] = data; size++; } void remove() { if (size == 0) { cout << "Queue is empty"<<endl; return; } else { for (int i = 0; i < size - 1; i++) { queue[i] = queue[i + 1]; } size--; } } void print() { if (size == 0) { cout << "Queue is empty"<<endl; return; } for (int i = 0; i < size; i++) { cout<<queue[i]<<" <- "; } cout << endl; } Queue operator+(Queue &obj) { Queue res; for(int i=0;i<this->size;i++) { res.add(this->queue[i]); } for(int i=0;i<obj.size;i++) { res.add(obj.queue[i]); } return res; } }; //your code goes here int main() { Queue q1; q1.add(42); q1.add(2); q1.add(8); q1.add(1); q1.print(); Queue2 q2; q2.add(3);...

char ** doubleIt (char **arr, int *maxsize); The doubleIt function will increase the heap size by doubling the original space. The functions takes 2 arguments: 1. A double pointer of type char called arr. This is a 2D dynamic array that contains words (strings) from the respective category (noun, verb, adjective, preposition). This is the original heap. 2. A pointer of type int called maxsize. This pointer holds the address of an integer that keeps track of the maximum amount of strings the 2D dynamic array can store. When this function is invoked, the current size of the dynamic array is at capacity so the values should match. This value will need to be multiplied by 2. The function allocates a new heap that is twice the size of the original heap and copy the values from the original heap into the new heap. One important note about this is that you have to properly copy the values over in order to avoid segmentation fault. Think about how this can be avoided. That is part of the...
