. C++ 11.A statement that displays the address of the variable num1 is Question 11 options: a) cout << &num1; b) cout << *num1; c) cout << num1; d) cout << &(*num1); 12.The statement int *ptr = new int; acquires memory to hold an integer and then Question 12 options: a) sets ptr to point to the allocated memory. b) assigns an integer value to the variable called ptr. c) initializes the allocated memory to 0. d) creates a new...
C Programming QUESTION 2 Which of the following statements about pointer arguments are true? Select all choices you believe are correct--this question may have more than one correct answer! A. The * operator allows you to access the address of an existing variable, while the & operator allows you to dereference a pointer and access the data to which it points. B. A function with pointer arguments must have the void return type. C. Pointer arguments allow you to write...
C++ Language 1. True/False: You can use pass by reference when passing a C++ unique pointer to a function. a)True b)False 2. True/False: A temporary value in a program can be referred to by at most one lvalue reference. a)True b)False 3. A unique pointer is a pointer a that is declared in a block of code in which it is the only pointer. b that is declared in a function in which it is the only pointer. c that...

Hi, this program is in C. Can you a pass by pointer in this program. Thanks. #include //function declaration/prototype here int main(int argc, char * argv[]) { int num1, num2; printf("Please enter two integers (separated by ,):\n"); scanf("%d,%d", &num1, &num2); //enter two integers separated by a comma (,) printf("num1 stores: %d\n", num1); printf("num2 stores: %d\n", num2); /*make a function call to make sure the followings are true after we call the function (1) variable num1 stores the larger value after...
Solve this problem using pointer variables wherever possible. to be completed in C Problem - sort 3 numbers Modify the sort 3 program you previously wrote, to use pointers. In main( ) read 3 numbers from the user into low, medium, high, then call a function to “sort” them. That is, if low = 50, medium = 10 and high = 30 before the function is called, then after the function call the variables will contain low = 10, medium = 30...
Question 1 (1 point) Which of the following is a reason to use functions? Question 1 options: To make it easier to read by keeping sections of code shorter. To avoid duplicating code. all of the above To make the code more organized. Question 2 (1 point) When the execution of a function ends, what Python code is executed next? Question 2 options: The function is automatically executed again. The line of code immediately after the end of the function....
Write a complete C++ program that will: Declare a vector of integers Use a pointer to dynamically allocate an array of 10 elements Ask the user how many values they would like to have in the data structures Read in the user’s response and make sure that it is greater than 20 (error loop) Generate the number of integers that the user asked for and store them into both data structures. The integer values should be unique unordered values (no...
1. A default constructor takes the same number of parameters as the number of private data members. Select one: True False 2. Select all that are true regarding passing an object to a function. Select one or more: a. A function cannot take multiple objects as parameters b. Passing by value creates a copy of the object c. Passing an object by pointer is not allowed d. Passing by reference allows the function to modify the object e. Passing by...
MUST USE C++ PLEASE READ THE QUESTION CAREFULLY!! ADD COMMENTS/EXPLAIN Question 1: Template Function with Pointer Arguments Design and implement a template function, called swapt(T *p1, T *p2), which takes two parameters with the same generic data type. The function swaps the values of these two parameters. Test this function in the following main( ) : int main( ) { int x = 30, y = 40; swapt(&x, &y); cout << “x = “ << x...
