Block has unique entry and exit points. Control always enters a basic block at its entry point and exits from its exit point. There is no possibility of exit or a halt at any point inside the basic block except at its exit point. The entry and exit points of a basic block coincide when the block contains only one statement. 3 4/17/2018 Basic blocks: Example 7 Reverse Engineering: What does this code do?

An edge (i, j) in E connects two nodes ni and nj in N. We often write G= (N, E) to denote a flow graph G with nodes given by N and edges by E. Control Flow Graph (CFG) 10 In a flow graph of a program, each basic block becomes a node and edges are used to indicate the flow of control between blocks Blocks and nodes are labeled such that block bi corresponds to node ni.

  • Control Flow Statements
    Control Flow Statements http://docs.oracle.com/javase/tutorial/java/nutsandbolts/flow.html http://math.hws.edu/javanotes/c3/index.html 1 Control Flow The basic building blocks of programs - variables, expressions, statements, etc. - can be put together to build complex programs with more interesting behavior. CONTROL FLOW STATEMENTS break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally execute particular blocks of code. Decision-making statements include the if statements and switch statements. There are also looping statements, as well as branching statements supported by Java. 2 Decision-Making Statements A. if statement if (x > 0) y++; // execute this statement if the expression (x > 0) evaluates to “true” // if it doesn’t evaluate to “true”, this part is just skipped // and the code continues on with the subsequent lines B. if-else statement - - gives another option if the expression by the if part evaluates to “false” if (x > 0) y++; // execute this statement if the expression (x > 0) evaluates to “true” else z++; // if expression doesn’t evaluate to “true”, then this part is executed instead if (testScore >= 90) grade = ‘A’; else if (testScore >= 80) grade = ‘B’; else if (testScore >= 70) grade = ‘C’; else if (testScore >= 60) grade = ‘D’; else grade = ‘F’; C. switch statement - - can be used in place of a big if-then-else statement; works with primitive types byte, short, char, and int; also with Strings, with Java SE7, (enclose the String with double quotes);

  • Chapter 3: Control Statements
    Chapter 3: Control Statements 3.1 Introduction In this chapter, you will learn various selection and loop control statements. Java provides selection statements that let you choose actions with two or more alternative courses. Java provides a powerful control structure called a loop, which controls how many times an operation or a sequence of operation is performed in succession. 3.2 Selection Statements Java has several types of selection statements: if Statements, if … else statements, nested if statements switch Statements Conditional Expressions 3.2.1 Simple if Statements if (booleanExpression) { statement(s); } // execution flow chart is shown in Figure (A) Example if (radius >= 0) { area = radius*radius*PI; System.out.println("The area for the circle of radius " + radius + " is " + area); } // if the Boolean expression evaluates to T, the statements in the block are executed as shown in figure (B) false false Boolean (radius >= 0) Expression true true Statement(s) area = radius * radius * PI; System.out.println("The area for the circle of " + "radius " + radius + " is " + area); (A) (B) FIGURE 3.1 An if statement executes statements if the Boolean Expression evaluates as true Note: The Boolean expression is enclosed in parentheses for all forms of the if statement. Thus, the outer parentheses in the previous if statements are required. Outer parentheses required Braces can be omitted if the block contains a single statement if ((i > 0) && (i < 10)) { Equivalent if ((i > 0) && (i < 10)) System.out.println("i is an " + System.out.println("i is an " + + "integer between 0 and 10"); + "integer between 0 and 10"); } (a) (b) Caution: o Adding a semicolon at the end of an if clause is a common mistake.

  • Conditional Statements
    Unit 5 Conditional statements Summary ² The if-else and if statements ² Block of statements ² Conditional expression ² Comparison between objects ² The switch statement 5.1 Statements in Java Till now we have seen two types of executable statements (without counting declarations): ² method invocation ² assignment These are simple statements by means of which we can write programs ² constituted by sequences of simple statements; ² that do method calls, possibly nested. Very often, when we have to solve a problem, we are interested in performing di®erent actions depending on whether certain conditions are true or false. 5.2 Conditional statements Java, like all other programming languages, is equipped with speci¯c statements that allow us to check a condition and execute certain parts of code depending on whether the condition is true or false. Such statements are called conditional, and are a form of composite statement. In Java, there are two forms of conditional statements: ² the if-else statement, to choose between two alternatives; ² the switch statement, to choose between multiple alternatives. 5.3 The if-else statement The if-else statement allows us to select between two alternatives. if-else statement Syntax: if (condition ) then-statement else else-statement ² condition is an expression of type boolean, i.e., a conditional expression that is evaluated to true or false ² then-statement is a single statement (also called the then-branch of the if-else statement) ² else-statement is a single statement (also called the else-branch of the if-else statement) 1 2 UNIT 5 Semantics: First, the condition is evaluated. If the result of the evaluation is the value true, the then-statement is executed, otherwise the else-statement is executed.
