Write a C-program that creates a calculator which can do addition, subtraction, multiplication, division and square. The user will have 6 options to give input for the choice of the task: "1" for the addition "2" for the subtraction "3" for the multiplication *4" for the division "5" for the square "6" for the exit The program will run in a while/for loop which exits with the input "6" Inside each task, you can ask for inputs of two numbers for the operation. For **square", you can just ask for 1 input number] Write a C-program that takes the heights of the 15 students in a class in an array and then sorts the values in a descending order.
