I've written the following C function but it is not working correctly. What did I do wrong? int *double5(void) { int i = 5; i = i *2; return &i;} Group of answer choices You can never return a pointer to a local variable. It's not possible for a function to return a pointer The variable has to be a global variable The function has to be of type void

For Assignment 5, you will design and write a program that covers the following topics: Functions, Vectors, Structures, and Classes. Functions & Passing Variables: Write a different function for each type of variable used. The functions should provide some sort of output through a cout or return value. Normal variable: Passing a variable by value to a paramater of a function. Show that this only makes a copy of the variable passed to it. Normal variable with a default value: Set a default value for a function parameter. Show how the default value gets used. Reference variable: Passing a variable by reference to a parameter of a function. Show how a reference variable can change the value of variable in main(). Show how the use of const can make a reference variable safer (think of it in terms of read/write). Pointer variable: Passing an address of a variable to a parameter of a function. Show how a pointer can change the value of a variable in main(). Show…

Choose if each of the following is true or false:Dynamically binding data to virtual functions is limited to pointers and references.
C++ Write a void function that has two parameters: a value parameter called num that receives a floating point number from the calling function and a floating point reference parameter called result. The functions should do this calculation: 25.0 * num + 37 and store the answer in result. Do not do any read or write operations in the function.
2. Safir Market wants you to create a simple python program for calculating Total cost and change for their customers. The program should start by reading price, articles and Money. Then you need to do the following: • Create a void function that will display "Safir Market" • Create a function with return value and with parameters that will compute Total cost as product of articles and price • Create a function that will accept the computed Total cost as a parameter and will compute the change. If the Total cost is more than or equal to Money, the balance is to be calculated as Money - Total cost, otherwise print the message 'Money not enough' • Display the output as shown below, Sample output Enter the price: 345 Enter number of articles: 4 Enter Money: 65 -Safir Market Total cost is: 1380.0 Money not enough Change is: None

Hello, I am having trouble with this homework question for my course for intro to c++. Topic is on Array 2, Write a function definition for a function named getPrev which does the following: 1) Accepts the array, size of the array and value as parameters. 2) Returns the value previous to a specified value in an integer array. If the specified value is the first element in the array, return -1. Example Given the array {10, 20, 30, 40, 50, 60}. Given the value 30, the getPrev function returns the value 20 which is the value previous to 30.
