Answer to Question #315367 in C++ for poato

Question

The program will need to calculate the final mark and corresponding grade and letter

grade based on the information given below.

• The final mark is derived from the following components of the assessments.

• Result calculation is based on information below:

o Exam (50%)

o Coursework (50%) components are made up of the total from the mid term test

(20%), programming assignment (15%) and lab practice (15%).

▪ Courseworks = Mid term test * 0.20 + Lab Practices (total marks /

150) * 0.15 + Programming Assignment * 0.15

▪ Final Mark = Exam * 0.5 + Courseworks

• Your program should also display the letter and letter grade based on the table

below:

Answer 1

int main()
{
	double totalmark;
	double exam;
	double midtermtest;
	double program;
	double labpract;
	double courseworks;
    int finalmark;
	cin >> totalmark;
	cin >> exam;
	cin >> program;
	cin >> midtermtest;
	labpract = totalmark / 150;
	courseworks = midtermtest * 0.20 + labpract * 0.15 + program * 0.15;
	finalmark = exam * 0.5 + courseworks;
	cout << "Grade" << endl;
	cout << "Percentage" << endl;
	cout << finalmark << endl;
	if (finalmark >= 0 && finalmark < 40)
	{
		cout << "F" << endl;
	}
	else if (finalmark >= 40 && finalmark <= 44)
	{
		cout << "D" << endl;
	}
	else if (finalmark >= 45 && finalmark <= 49)
	{
		cout << "C-" << endl;
	}
	else if (finalmark >= 50 && finalmark <= 54)
	{

	}
	else if (finalmark >= 55 && finalmark <= 59)
	{

	}
	else if (finalmark >= 60 && finalmark <= 64)
	{

	}
	else if (finalmark >= 65 && finalmark <= 69)
	{

	}
	else if (finalmark >= 70 && finalmark <= 74)

	}
	else if (finalmark >= 75 && finalmark <= 79)
