Lab on void functions Write a void function called CaleAverage that has three test scores as input (parameters) and calculates the average. The average will be displayed inside the function itself. Hint: Read the three test scores inside the main and pass them to the function called CalcAverage, which calculates the average and displays it inside( 16 points) Problems on Void Functions 1. Write program to print out the appropriate activity depending on the temperature. (16 points) 2. temp> 8:5 temp> -70 but less than 85 - tennis temp > -32 but less than 70 -golf temp >-0 but less than 32 skiing else(none of these temperatures apply) - swimming go for dancing You have to write a function called PrintActivity that will take the temperature as input and pass it to the function. It will then determine what activity to be done inside of the function and print it inside the function. Remember this is a void function Pseudo code: 1. Write prototype for the function 2. Read temperature from the user 3. Pass the temperature to the function 4. Decide the activity and print it put on the screern Write a program to swap two numbers x and y. a. (16 points) b. You should read in two numbers from the key board and pass them to a function called Swap. c. Swap them inside the function and print them out in the function d. Print them in the main also. Did they print out the same values in the main and in the function? If not, why? e
