Create two functions to calculate the area and circumference of the circle using pointer. - Area (): this function will accept radius as parameter to calculate area of the circle. - Circumference (): This function will accept radius as parameter to calculate circumference. Write a main function that accept radius value from the user. The user may either choose a calculation of area or circumference of circle (use switch statement to handle the choice). The result will be displayed to the user by respective function calling. Note: Create constant for PI value. Language C

Which function does not return the pointer correctly?The code below calls the getline member function of cin to read a line of characters from cin into an array of characters up to a certain limit specified as the second parameter of the call.Your job is to find out if the pointer returned from the function can still be used by the caller of the function to access the memory that is pointed to by the pointer.char *getName() { char buf[80]; cout << "Enter your name: "; cin.getline(buf, 80); return buf;}char *getName() { char buf[80]; cout << "Enter your name: "; cin.getline(buf, 80); return buf;}char *getName() { char *buf = new char[80]; cout << "Enter your name: ";cin.getline(buf, 80); return buf;}None of thesechar getName(char buf, int size) { **cout << "Enter your name: ";cin.getline(buf, size);return buf;}
(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 address
The following is the difference between void and NULL pointers: Use relevant examples to back up your statement.
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

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) { }

In the following program with struct student, which has name and age. There is a pointer to struct student *ptr, but does not assign a value to it. Then, there is a print statement for ptr->age. 1. Why does an error occur when the program is run? #include <stdio.h> //make struct student struct student { charname[25]; int age; }; int main() { //declare pointer to struct student struct student *ptr; //print ptr -> age printf("%d", ptr->age); return0; }
python: In this assignment, you will use a dictionary called balances to track money balances for people (think of it as a very insecure banking interface). This dictionary will be a global variable in your script. You will create two functions, depositMoney() and withdrawMoney(), that will be used to manipulate this dictionary to add or subtract money from a person's account. These functions will return a tuple of information. The functions you need to create are described in the function specifications below. Function 1: depositMoney(name, amount) """ Given a person's name and amount of money, adds amount to their account. If person does not have an account, one is created for them. Parameters: name - string amount - float, amount >= 0 Returns: bool - True if account existed, False if account had to be created float - new balance for person """ Function 2: withdrawMoney(name, amount) """ Given a person's name and amount of money, withdraws amount from their account. If…
