Subsection 1.16.1
Given
int alpha = 2, beta = 1, delta = 3, eta, gamma;
double omega = 2.5, theta = -1.3, kappa = 3.0, lambda, rho;
Exercises Exercises
1.
Q32: delta += omega;
Why is this statement invalid?
cannot assign a double to an int variable
eta does not have a value
eta is a constant
cannot assign an int to a double variable
2.
Q33: alpha *= beta + delta;
What is the value of alpha?
