From your previous programming experience, you should be reasonably comfortable with the operators that have been used so far. The full set of operators are enumerated later in this chapter. Precedence Operator precedence defines the order in which an expression evaluates when several different operators are present. The easiest to remember is that multiplication and division happen before addition and subtraction. After that, if an expression isn't transparent to you it probably won't be for anyone reading the code, so you should use parentheses to make the order of evaluation explicit.
Shortcuts can make code much easier to type, and sometimes much harder to read.
Perhaps the C language designers thought it would be easier to understand a tricky piece of code if your eyes didn't have to scan as large an area of print. You often use these to change loop variables, which control the number of times a loop executes. Corp. All Rights Reserved.
