Activity 1 This program firstly initializes an object of struct Cirele with values and then updates those using pointers. The program uses structure notation once and pointer notation another afterwards. #include #include #define MIN 1 #define MAX 30 struct Circle { float xCoord; float yCoord; float radius; }; /* prototypes */ float getRandomNumber (int min, int max); void printByValue(struct Circle cirobj); void setValue(float *target, float newValue); void printByReference(struct Circle *cirObj); int main(void) { /* Declare a struct circle and name it circleobject */ struct Circle circleObject; /* Fill circleObject's members with random numbers */ circleobject.xCoord = getRandomNumber(MIN, MAX); circleobject.yCoord = getRandomNumber (MIN, MAX); circleobject.radius = getRandomNumber (MIN, MAX); /* Printing values of the circle by calling function print by value */ printByValue(circleobject); /* update values of circle one by one */ setValue (&circleobject.xCoord, getRandomNumber(MIN,…

: An animal shelter, which holds only dogs and cats, operates on a strictly"first in, firstout" basis. People must adopt either the "oldest" (based on arrival time) of all animals at the shelter,or they can select whether they would prefer a dog or a cat (and will receive the oldest animal ofthat type). They cannot select which specific animal they would like. Create the data structures tomaintain this system and implement operations such as enqueue, dequeueAny, dequeueDog,and dequeueCat. You may use the built in Linkedlist data structure.
struct Info { int id; float cost; }; Given the struct above, the following code segment will correctly declare and initialize an instance of that struct. Info myInfo = {10,4.99}; Group of answer choices True False ============== Consider the following code fragment. int a[] = {3, -5, 7, 12, 9}; int *ptr = a; *ptr = (*ptr) + 1; cout << *ptr; Group of answer choices 4 -5 3 Address of -5 =============== What will happen if I use new without delete? Group of answer choices The program will never compile The program will never run The program will run fine without memory leak None of these
