Suppose x, y, and z are int variables and x = 18, y = 5, and z = 4. what is the output of each of the following statements? (3, 4, 10)

a. cout << "x = " << x << ", y = " << y << ", z = " << z << endl;
b. cout << "5 * x - y = " << 5 * x - y << endl;
c. cout << "product of " << x << " and " << z << " is " << x * z << endl;
d. cout << "x - y / z = " << x - y / z << endl;
e. cout << x << " square = " << x * x << endl;
