TRUE OR FALSE, C++ When passing an array to a function, you must include & in front of the array name. When passing an array to a function, you must include & in front of the array name. It is possible to have a 2-dimensional array where each row has a different number of columns. The * is called the address of operator.

Programming: Simple Arrays Assignment Instructions Overview You will use the enumerated type and a switch to calculate the weight someone would have on another planet. Instructions Use a functional decomposition to write a C++ program that asks the user to enter his or her weight and the name of a planet. Use an enumerated type called planetType to represent the planets and use a switch statement that takes as its condition a planetType variable. The program, via the switch statement, then outputs to the screen how much the user would weigh on that planet. The following table gives the factor by which the weight must be multiplied for each planet. Your program must have the following functions in it: GetUserInput() ConvertInputToPlanetType() OutputWeight() (your switch statement must be in OutputWeight()). Determine what each function’s parameters and return types should be. The program will output an error message if the user does not type a correct planet…
Topic: Array covered in Chapter 7 Do not use any topic not covered in lecture. Write a C++ program to store and process an integer array. The program creates an array (numbers) of integers that can store up to 10 numbers. The program then asks the user to enter up to a maximum of 10 numbers, or enter 999 if there are less than 10 numbers. The program should store the numbers in the array. Then the program goes through the array to display all even (divisible by 2) numbers in the array that are entered by the user. Then the program goes through the array to display all odd (not divisible by 2) numbers in the array that are entered by the user. At the end, the program displays the total sum of all numbers that are entered by the user.
C++ Coding: ArraysTrue and False Code function definitions for eoNum() and output(): Both eoNum() and output() are recursive functions. output() stores the even/odd value in an array. Store 0 if the element in the data array is even and store 1 if the element in the data array is odd. eoNum() displays all the values in an array to the console.

Part 4: Arrays Program c++ Write a program which takes 2 arrays of 10 integers each, a and b. c is another array with 20 integers. The program should put into e the appending of b to a, the first 10 integers of e from árray a, the latter 10 from b. Then the program should display the array c, then find and display the Minimum value of the array c. ANSWER
program Credit Card Validator - Takes in a credit card number from a common credit card vendor (Visa, MasterCard, American Express, Discover) and validates it to make sure that it is a valid number (look into how credit cards use a checksum) - it's a C++ program so use #include <iostream> - And please use an array, use files, and use pointers in this program. -

C++ Programming. OVERVIEW OF DATA STRUCTURES. Task: Write a program to process a data array. Execute a custom task as a separate function or method of a custom class. When performing a task, use functional methods for manually entering array elements, generating random numbers, and printing array elements. Given an array of size N. Create a function to determine the element that is furthest from the arithmetic mean of the array elements (that is, the maximum absolute difference).
Part 1 //Program Statment: Write a program(in c++) that first reads an integer for the array // size , then reads numbers into the array, and displays distinct numbers (i.e.// if a number appears multiple times, it is displayed only once). (Hint: Read // a number and store it to an array if it is new. If the number is already in // the array, discard it. After the input, the array contains the distinct numbers.) Part 2 //Program statment: When array is created, its size is fixed. Occasionally, you//need to add more values to an array, but the array is full. In this case , you //may create a new larger array to replace the existing array. Write a function //with the header;// // int * doubleCapacity(const int *list, int size)// //The function returns a new array that doubles the size of the parameter list.
