In this lab you are to write a program that calculates a student's final grade and outputs the final letter

grade to the console using functions. Two tests scores and one homework score will be supplied by the

user. To calculate the final score assume that the tests are each worth 40% and the homework is worth

20% of the total score. You should implement and use the following two functions:

1) calcFinalScore: This function is a value-returning function whose purpose is to compute the

final score for a student. It takes three parameters: test1, test2, and hw (all doubles), and returns

the final score as a double.

2) printFinalScore: This function is a non value-returning function that outputs a student's final

score and letter grade to the console. It takes the parameter finalScore (a double).

The breakdown of letter grades is as follows: 90 or above is an A, 80 to 90 is a B, 70 to 80 is a C,

60 to 70 is a D, and less than 60 is a big fat F.

The following is skeleton code you might want to use to start your program.

#include

using namespace std;

// ***declare the function prototype for "calcFinalScore" here

// ***declare the function prototype for "printFinalScore" here

int main()

{

// local variables

double test1, test2; // the two tests scores

double hw; // the homework score

double finalScore; // the student's final score

cout << "Enter the score for test #1: ";

cin >> test1;

cout << "Enter the score for test #2: ";

cin >> test2;

cout << "Enter the score for the homework: ";

cin >> hw;

// ***call calcFinalScore here

// ***call printFinalScore here

system("PAUSE");

return 0;

}

// ***implement calcFinalScore here

// ***implement printFinalScore here

The following is a sample run (bracketed bold text denotes user input):

Enter the score for test #1: [87.5]

Enter the score for test #2: [82]

Enter the score for the homework: [95]

The student's final score is: 86.8

Their final letter grade is: B
