Exercise 1 - Passing variables By Reference (Calling By Reference) (2 marks) Exercise Objectives Declaring pointer variables Assigning pointer variables with references Accessing values using pointers Passing variables by reference Calling functions by references Using references to allow functions to return many values (in/out variables) Problem Description Open replit.com IDE, create a new repl (project) and name it "Lab115x1". Use this project to write and run a C program that performs the following: Declare the following functions as prototype and implement them after the main function SwapNums(), a function that receives two real (float) pointers a, b, and swaps them. [Note: This function not used to print values, just swap a and b] PerformCalc(), a function that receives two real numbers a, b and returns their addition, subtraction, multiplication and division values. (Hint: Your function prototype should be like this: void PerformCalc(float a, float b, float add, float sub, float .mul, float .div); (Note: in the same function you need to deal with division by zero problem) In the main function declare two real (float) numbers and y, and prompt the user to read both of them, then call the functions declared above as follows: Call Swap Nums() by passing the addresses of x and y o Call PerformCalc() function for x and y [Declare 4 float variables a, s, m, d to be passed as references in order to hold the addition, subtraction, multiplication and division values. ] Organize the output to appear as shown in the sample output below Download your project as .zip file and keep it within your file system (Desktop for example) Upload the project to the eLearning platform Sample Output Input the value of x 33.4 Please enter the value for y 17.9 After swapping x becomes 17.9 y becomes 33.4
