In this way, a program doesn't operate the exact same way step-by-step each time it is run. This is where If-Else statements come into play. An If-Else statement can be used to allow the computer to perform a different set of actions depending on whether a condition is true or false. If-Else statements follow the following general syntax:. When implementing If-Else statements, it is very important that conditions be in parenthesis.
Conditions are required following an if and else if and are not allowed for elses. If statements are required while you can have none or multiple else ifs and elses, depending on the particular algorithm you are implementing. Brackets are required to enclose multi-lines although are unnecessary if you only have a single statement being executed following each condition.
The above is a very simple segment of code which prints Hello! Therefore, x will always be less than 4, and only Hello! The else statement, implying that x is not less than four, is completely overlooked. Note that two sets of brackets enclosing the two cout statements are optional, as only one statement of code is to be executed under each condition.
If, for example, ten different operations were to occur if x was less than 4, those ten statements would be enclosed in brackets. If-Else statements can be nested inside one another. When dealing with them, they are best not taken line-by-line, but rather as a nested hierarchy of components to be taken piece by piece.
Switches Yet another form of branching can be expressed in the form of a switch statement. In such a case, there are a set number of posibilities. The computer runs down the list from the first down to the last until the condition being tested is met. Once this condition has been "found," directions are executed. The numbers 1, 2, and 3 after the word case are the values which the computer is testing to see if number is equal to. For example, if number is equal to 1 when the program enters the switch, the computer will print out "the value is one.
A truth table for a function of n variables has 2 n rows. Boolean algebra. Boolean algebra refers to symbolic manipulation of expressions made up of boolean variables and boolean operators. The familiar identity , commutative , distributive , and associative axioms from algebra define the axioms of Boolean algebra, along with the two complementary axioms. In addition, you can derive many other laws from these axioms. Boolean algebra in Java.
You can incorporate Boolean algebra into your Java programs, in two different ways. Bitwise operations on integer values: In Section 6. Boolean functions of three or more variables. As the number of variables increases, the number of possible functions increases dramatically.
