A programmer implemented a swap function in C as follows: void swap(int x, int y) { int temp; temp = x; x=y; y = temp; } However when he tried to use the swap function in the main function as given below, it didn’t work. int main () { int a=10, b=20; swap(a,b); ... } i. Explain why this function doesn’t work. ii. Suggest a way of fixing it.

Write a C program that creates a security access code from a social security number entered by a user as follows: Using a recursive function it adds all of the digits of the social security number and then using a regular function gets the square number of the sum and displays it. The access code displayed should be initialized as an integer number but using type casting is displayed as a floating number.

C++ Programming: Write a recursive function, sumDigits, that takes an integer as a parameter and returns the sum of the digits of the integer. Also, write a program to test your function. Your program should prompt the user for an integer and output the results to the console.
In C programing Write a recursive function that returns the product of the digits of its integer input parameter, n. You may assume that n is non-negative. For example, productDigits(243) should return 24, since 2 x 4 x 3 = 24.int productDigits (int n) {
in C++ oop explain return by ( address , value , reference , etc... ) and pass by ( address , value , reference , etc... ) whats the difference and how i can determine which is the function condition.
Write a C program that takes a command line argument of a number that you need to calculate the factorialvalue of. The program must use a recursive function to calculate the result and then print the result tostandard output. The program must perform the following functionality:1. Create and save a new C program called factorial.c2. Correct type definition for recursive function. [1]3. Correct type definition for main function to process input arguments. [2]3This document may not be used or reproduced without permission from the University of Johannesburg4. Correct type definitions for variables. [1]5. Ensure command line arguments to read in the input number to calculate the factorial is used.[1]6. Test if the correct number of input arguments are entered when the program is called and print an errormessage if insufficient arguments are entered. [2]7. Convert the string to a number and test the entered number is not a negative number and print an errormessage if negative. [2]8.…
Write a C program that generates a social security code from a user's entered social security number: It adds all the digits of the Social Security Number using a recursive function and then shows the square number of the sum using a normal function. The displayed access code should be initialized as an integer number, but it is shown as a floating number by form casting.

Create a function in C++ using recursion where the user inputs a number. The function will repeat an equation where you get the square root of a number for the amount of loops selected. A random number between 1-10 will be used to determine the length of the loop.
Java C++ Write a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition: 7∗4=4+4+4+4+4+4+47 * 4=4+4+4+4+4+4+47∗4=4+4+4+4+4+4+4
Using a pointer as the return value is considered a poor practise in C. For example, how does dynamic memory allow us to return an object pointer from a function safely?
