Call your readChar function to get user's response. 5. getStudentAverage function Code a void function that uses two reference parameters to return a name of type string& and an average of type double& to the calling environment. This function will: - Prompt for and get the student's name by calling the string class getline function. - Prompt for and get the four test scores for the student by calling the readint function for each test score and storing each in a local variable - will need four local variables. A valid - test score will be in the range 0 to 100. - Pass the four test scores to the min function to find and return the minimum score. - Calculate the total of the highest three test scores. - Call the average function to calculate the average of those three scores. - Return the student's name and the test average to the calling environment (main in this case). 6. displayStudentAverage function Code a void function to display information to the screen. This function should receive as value parameters the student's name and average and display those values to the screen along with identifying text. Display the average with one decimal digit of precision.

First, read through the entire assignment and develop a HIERARCHY CHART of the function calls and the data that will be passed between them. Submit this chart for grading. This may be hand drawn and submitted on power. Create a new programming project and add your library files to it. Next code the following two functions as described below. Apply bottom-up design coding main driver routings for testing each of the following functions. Comment out and keep the driver test code and results for later review. 1. average function Code a generic, reusable value returning function of type double that has two value parameters; a double for the sum total of the values to average and an integer for the count of number of values to be averaged. The function will calculate and return a floating-point average as a double. Check for invalid division by zero. If a valid average cannot be calculated, the function should return 0.0. When fully implemented and tested, move to your library files. 2. min function Code a generic, reusable value returning function of type int that has four value parameters to receive four integers. The function will use IF selection statements and the logical operators (AND) && and/or (OR) II, and relational operators (, >=) to find and return the lowest of four integer values received. (Do NOT code to use an array structure or code without using either the && or II operators!) When fully implemented and tested, move to your library files. - TEST THOROUGHLY!!! Include test sets with values in ascending, descending and mixed orders and a set with all values the same amount. When fully implemented and tested move to your library files. - TEST THOROUGHLY and keep test code. 4. main function Code a main function with the following user interface according to the specification given below: Program Calculates the average of 4 Tests after Dropping the Lowest Score.
