5. pointers, structs and arrays Given the definition struct Animal { char * species; int age; }; and the following animals: 5 year old gorilla 11 year old giraffe 4 year old cobra 2 year old gnu 8 year old lion Give a description in word AND draw a picture for each of the following declarations. Be sure to include the complete data for the animals described above. a) struct Animal zoo[5]; b) struct Animal * zoo2[5]; c) struct Animal (* zoo3)[];

Exercise 2 This exercise is designed to assess student’s skills of writing programs using arrays and loops. Write a C++ program using array and loop that prompts a user to enter 15 Students’ marks in ProgramDesign and Implementation (PDI) Module in an array. The program sorts the students’ marks in descending order using a loop and displays the marks of all students as well as lowest, highest, average marks, and the class result based on the average module marks. The result criteria is given below:Average is less than 40 = Poor ResultAverage is between 40 to 49 = Fair ResultAverage is less than 50 to 59= Good ResultAverage is less than 60 to 69 = Very Good ResultAverage is between 70 to 79 = Excellent ResultAverage is 80 or greater = Outstanding ResultNote: You must demonstrate the use of arrays and loops. Your code must be properly commented Sample Output:Welcome to Result Management SystemEnter PDI Marks of Student 1: 50Enter PDI Marks of Student 2: 35Enter PDI Marks of Student 3:...

Explain the values of int data type.

Question 6 Arrays in c++ can contain different data types (a single array with different data types). O True O False

Language: C++ Also, create two hurricane objects in the main function and print the average wind speed of them. All the data members can be public.

Programming in C

In C++ struct myGrades { string class; char grade; }; Declare myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: "Math" "Computers" "Science" "English" "History" and give each class a letter grade

Declare a student structure that contains : Student's first and last nameStudent IDCreate the following functions: getStudentInfo(void) Declares a single student, uses printf()/scanf() to get inputReturns the single student backprintStudentInfo(student_t *st_ptr) Takes the pointer to a student (to avoid making a copy)Prints out all of the student informationDeclare an array of five studentsUsing a for loop and getStudentInfo() function, get input of all the studentsUsing a for loop and printStudentInfo() function, print all the output of all students.

typedef _people { int age; char name[ 32 ] ; } People_T ; People_T data [ 3 ]; Using string lib function, Assign 30 and Cathy to the first cell, Assign 40 and John to the second cell and Assign 50 and Tom to the third cell People_T *ptr ; Declare a pointer pointing to the structure data and print the age and name using the pointer. your output can be : 30 Cathy 40 John 50 Tom

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,...

#include <iostream>using namespace std; struct Person{ int weight ; int height;}; int main(){ Person fred; Person* ptr = &fred; fred.weight=190; fred.height=70; return 0;} What is a correct way to subtract 5 from fred's weight using the pointer variable 'ptr'?
