- 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. -The following is the difference between void and NULL pointers: Use relevant examples to back up your statement.The following describes the difference between void and NULL pointers: Make proper use of examples to bolster your argument.
- Trace these print statements using the following arrays. Write "error", if an error occurs.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.What is a variable pointer? What follows? It is a variable array. Why are pointers and dynamic arrays problematic?
- Which operations are not possible with pointers?Note: Don't use functions AND pointers.Finish the swap function below using pointers and write the call to swap in the reverse function using the address of the array positions array[i] and array[size-i-1].using pointers. DON'T FORGET TO DECLARE THE PARAMETERS in the function. (Hint: if you can't figure it out with pointers, do it with the references #include <iostream>using namespace std; // Function to swap two ints using pointers// @param pointer to an int// @param pointer to an intvoid swap( ) {// TODO: Add code that swaps two integers using pointers } // Function to reverse arrayvoid reverse(int a[], int size) {for (int i = 0; i < size/2; i++) {// TODO: write the call to swap in the reverse function using the // address of the array positions array[i] and array[size-i-1].
- Indicate true or false for the following statements: a. Every element in an array has the same type. b. The array size is fixed after an array reference variable is declared. c. The array size is fixed after it is created. d. The elements in an array must be of a primitive data type- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) write a c++ program named "isTheLastNumberTheMax" that accepts an array of integers and its size. It will return true if the last number in the array is the maximum number in that array and false otherwise. In addition, it also returns another boolean to indicate whether this list contains more than one maximum value.For example, if this is called with the array of {10, 20, 30, 40, 50}, it will return true and falseIf this is called with the array of {50, 10, 20, 30, 40, 50}, it will return true and true.AHPA #10: The Secure Array * * Using pointers, access Peter's array without him knowing it * and place three values that you got from the user (101, 63, * 21) at locations 3, 6, and 9. Recalculate the sum value and * update it. ( the output should be same as the picture)
