Evaluation of a Second-Degree Polynomial
To develop a better understanding of the rules of operator precedence, consider the evaluation of an assignment expression that includes a second-degree polynomial ax2 + bx + c:
The multiplication operations are evaluated first in left-to-right order (i.e., they associate from left to right), because they have higher precedence than addition. (Java has no arithmetic operator for exponentiation in Java, so x2 is represented as x * x. Section C.16 shows an alternative for performing exponentiation.) The addition operations are evaluated next from left to right. Suppose that a, b, c and x are initialized ...
