Objectives: This lab is designed to enforce the concept of functions. The students will learn about: Writing functions. Tracing through a program. Passing the parameters to functions. Writing functions to return data. In Z Laboratory: Write the following two programs using functions to perform the task: Program 1: Write a program that inputs three coefficients of a quadratic equation and then calls a function that prints the roots of the equation. The functions should print the roots for all three possible cases. Problem 2: Write a function that evaluates ex as 1.0 + x/1! + x2/ 2! + x3/3! + ...xnn!. Write a main program where user inputs number of terms and value of x and passes to the function. The function evaluates ex and returns the result to the main program where it is printed. The main program should use a sentinel loop to call the function several times. Write both above described programs, compile and execute them and show the result to your instructor. Report is required for this laboratory
