COM 1100 Professor Fell Homework Exercises 1 Solution

Problems 1, 2, 3, and 4 Problem 5:Construct a logical expression to represent each of the following conditions:

a. score is a passing grade, i.e. between 60 and 100)
(60 <= score) and (score <= 100)

b. number is divisible by 2 but not by 3
(number % 2 == 0) and (number % 3 != 0)

c. angle is between ¹ and 2¹
(pi < angle) and ( angle < 2 * pi)

d. response is either 'Y' or 'y'
(response == 'Y') or (response == 'y')

e. ch is a digit
('0' <= ch) and (ch <= '9')

f. tired but not done
tired and not done

Problem 6:

int min3(int x, int y, int z){
	if ((x <= y) and (x <= z )) 
		return x;
	if ((y <= x) and (y <= z )) 
		return y;
	return z;			
}

Problem 7:

bool GetCircleData(int& x, int& y, int& radius){
	cout << "Enter circle data:  x  y  radius" << endl;
	cin >> x >> y >> radius;
	return (radius >= 0);
}

Problem 8:

 
void extremes(int& min, int& max, int A[], int n){
	min = A[0];		// start min and max with values that occur in the array
	max = A[0];
	
	for (int J = 1; J < N; J++){
		if (A[J] < min)
			min = A[J];
		else if (A[J] > max)
			max = A[J];
	}
}
