Thread: Another c++ question that i can't figure out

theta += delta_theta

does this mean;

1) delta_theta = 2 * theta

or

2) theta = .5 * delta_theta

or

3) something else entirerly

it means:
theta = theta + delta_theta

or in words:

theta is assigned the value of theta plus the value of delta_theta

thanks again another one solved.....
