Subsection 4.2.1

Each question below is independent, but they all use this given setup
int alpha = 2, beta = 1, delta = 3, eta = 0, gamma = 0;
double omega = 2.5, theta = -1.3, kappa = 3.0, lambda = 0.0, rho = 0.0;

Exercises Exercises

1.
Q1: What is the value of rho after executing the following code?
if (theta > omega)
    rho = kappa + 2;
2.
Q2: What is the value of eta after executing the following code?
if (beta<alpha)
    eta = 42;
3.
Q3: After executing the following code, the value in variable eta is and the value in variable beta is .
if (kappa<delta)
    eta = 42;
    beta = 22;
4.
Q4: After executing the following code, the value in variable eta is and the value in variable beta is .
