Question 3) Write a user defined function called Maximum. The function takes two parameters. Two parameters are integer pointer reference values. The function determines which of the two values is bigger. The function will display a message stating which value is bigger. If pointers aren't used, then no credit will be given.

Step by step
Solved in 3 steps with 1 images
- 1. Inspect the code and in your own interpretation, describe the reason call to functionChangeIt_1(n) will not change x in main()? 2. Inspect the code and in your own interpretation, describe the reason parameter n inChangeIt_2(int *n) is a pointer, and statement in the function is *n = 6 ? 3. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 4. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.1) Write a complete program that will have a main function and a function called twice. a. Write a function named twice whose only parameter is an integer pointer.b. This function doubles the value stored at the location pointed by the pointerparameter.c. In the main method, declare an integer variable num and initialize it to 5. Call thefunction twice from main such that the function twice will double the value of num.d. In the main method and after calling the function, print the variable num.
- Write a statement that declares a prototype for a function divide that takes four arguments and returns no value. The first two arguments are of type int. The last two arguments arguments are pointers to int that are set by the function to the quotient and remainder of dividing the first argument by the second argument. The function does not return a value.In this part your will have questions about C++ functions with pointers. • Write a function that takes three integer pointer as parameters and calculates sum of all numbers. This function must return the result as a pointer. • Declare a structure about a book which has properties such as name and price etc. Then create a list of book with 5 books. After that define a function that takes this book-list as a pointer and print out list items. • Write a function that calculates total price of the book in the book list (note: take the book-list as a pointer again). Write all function prototypes and test all functions within a single main functions.Run the following program and answer the questions. #include <stdio.h> int main() { int a[5] = {4,16,19,12,16}; int *arr_pointer = &a[0]; *arr_pointer = a[*arr_pointer]; arr_pointer++; printf("%d\n", *arr_pointer); return 0; } 1. For each line of the main function (lines 5 through 8 in particular), consider how the variable a changes as the program progresses. Explain what the value of a is at each major line and why it has such value. (Hint: the gdb step command is very helpful for this problem).
- Write a function dispense_bills(). The function determines the minimum number of bills to dispense given a withdrawal amount. The possible bills dispensed include: 50’s, 20’s, and 10’s. The number of each bill to dispense should be stored indirectly through the pointers: fifties_ptr, twenties_ptr, and tens_ptr. If the withdrawal_amount exceeds the balance, then the number of each bill to dispense should be set to 0, and 0 should be returned. If the withdrawal_amount is less than or equal to the balance, then the number of each bill to dispense should be calculated, and 1 should be returned. The function header has been provided for you. // precondition: withdrawal amount must be a multiple of 10 // return: 1 if the balance >= withdrawal_amount; 0 otherwise int dispense_bills(double balance, double withdrawal_amount, int *fifties_ptr, int *twenties_ptr, int *tens_ptr) { }Pointers are by default passed by value in a function. Group of answer choices True False ================= Given the below code segment, which of the following would allow you to deallocate all memory allocated to the pointer numbers? int* numbers = new int[5]; Group of answer choices delete[] numbers; delete numbers; delete[5] numbers; None of these ========== Consider the following code: int arr[][4] = { {1, 2, 3, 4}, {7, 8, 9, 10} }; cout << arr[1] << endl; What will be the output? Group of answer choices 1 7 Address of 1 Address of 7 Compilation error: Second [] bracket missing with arrPLEASE WRITE THIS IN C Please read the following: Has to have the two functions as stated below, and has to use pointer notation! Include two functions in your program, one which demonstrates the functionality using pointer notation and one which demonstrates the functionality using array indexing. The function prototypes are below: void copyArrayIndexWay(char * const newArray1, const char * const originalArray1); void copyPointerWay(char *newArray2, const char *originalArray2); char originalArray1[] ="COMP10120"; char originalArray2[] = "COMP10110"; Include relevant print statements to explain the difference between the two functions and provide a nice output with the results.. Attached image of full question:
- 1. What is the purpose of the new operator? 2. True/False: if you use the new operator, you later should use delete. Why or why not? 3. True/False: When you add 1 to a pointer using the ++ operator, you are actually adding the size of the data type referenced by the pointer 4. You are reading a program which includes the following lines: int size = 5;int *cards = new int[size]; Which of the below statements is true: a) int *cards is a function to print cards b) If there is no delete statement anywhere else in this program, this program has a memory leak. c) The program won’t compile if there is no delete statement elsewhere in this program. d) None of the above(a) Determine whether the following variable declaration is valid int INT; A Valid B Invalid (b) Determine whether the following variable declaration is valid. int *ptr; A Valid B Invalid (c) Which of the following statement about pointer is TRUE? A. A pointer variable is a variable used tostore an address B.A pointer holds the data, rather thanwhere to find the data C.The unary operator & is used to find anobject's value D.The unary operator * is used to find an object's addressC Programming-Plz fix this code We can return multiple values from functions using pointers. Let's see an example. # include <stdio.h> void add Gr.marks (int * m) { *m = * m + 10; } void main ( ) { int marks; clrscr ( ); printf("enter actual marks:"); scanf(" % d", & marks); add Gr.marks (& marks); printf(" \n the graced marks is :\t % d", marks); }
