===================================================================================================
Program 2:
what student should do:
Write a program that calculates the average of three test scores. The program should contain
three value-returning functions: main, getTestScore, and calcAverage. The main function
should call the get TestScore function to get, validate the score to make sure the value is
between 0 and 100, and return each of the three test score. The testscore may contain a decimal
place. (Hint: the main function will need to call the getTestScore function three times.) The
main function then should call the calcAverage function to calculate and return the average of
the three test scores. When the calAverage function has completed its task, the main function
should display the average on the screen.
Submit a copy of the program (30 points) and a copy of the program output for different
data sets. Make sure you include output for invalid test scores (10 points).
=================================================================================================================
//function prototypes
float getTestScore ( );
float calcAverage(float score1, float score2, float score3);
int main( )
{
float s1, s2, s3; //these variable are used to store test scores
float average;
//call getTestScore function to get the test scores
s1 = getTestScore();
s2 = getTestScore();
s3 = getTestScore();
//call calcAverage to calculate the average of three test scores
average = calcAverage(s1, s2, s3);
// display the average
cout << "average of three test scores ("< Our website has a team of professional writers who can help you write any of your homework. They will write your papers from scratch.
