One of the reasons compound operators are useful is that not only they provide a shorter way for operations, but also implicitly cast variables.
Formally, a compound assignment expression of the form: Let’s review why the last line won’t compile.
Before writing a program to solve a problem, you should have a thorough understanding of the problem and a carefully planned approach.
In this chapter, you will learn the theory and principles of structured programming with control statements.
There are two ways Java evaluates the compound operations.
How Do You Do Homework - Compound Assignment
First, when the left-hand operand is not an array, then Java will, in order: at the end of the assignment.Compound-assignment operators provide a shorter syntax for assigning the result of an arithmetic or bitwise operator. *= assigns the result of the multiplication /= assigns the result of the division. They perform the operation on the two operands before assigning the result to the first operand. Note that Compound assignment to an enumerated type generates an error message.If the left operand is of a pointer type, the right operand must be of a pointer type or it must be a constant expression that evaluates to 0.Selection Statements 4.8 Repetition Statements 4.9 Compound Assignment Operators 4.10 Formulating Algorithms: Counter-Controlled Repetition 4.11 Formulating Algorithms: Nested Control Statements 4.12 Using the Debugger: Locating a Logic Error 4.12.1 Breakpoints and Running the Program 4.12.2 Before writing a program to solve a problem, you should have a thorough understanding of the problem and a carefully planned approach.When writing a program, it's also important to know the available building blocks and to use proven program-construction principles.You'll learn how to view the values of variables during a program's execution, how to step through code one statement at a time and how the debugger can help you locate logic errors in your programs.The compound-assignment operators combine the simple-assignment operator with another binary operator.In this chapter and the next, we present the theory and principles of structured programming with control statements.We introduce the control and use it to display and process data, such as a list of grades in a class-average program.
