Chapter 3 Lab Decision Structures Lab objectives Be able to construct boolean expressions to evaluate a given condition Be able to compare string objects Be able to use a flag Be able to construct if and if else if statements to perform a specific task a switch statement Be able lo construct Be able to format output Introduction Up to this point, all the programs you have written had a sequence structure. This means that all statements are executed in sequence, one afte another. Sometimes we need to let the computer make decisions, based on the data A decision structure allows the computer to decide which stalement In order to have the computer make a decision, it needs to do a comparison So we will work with writing boolean expressions, boolean expressions use relational operators and logical operators to create a condition that can be evaluated as true or false Once we have a condition, we can conditionally execute statements This means that there are statements in the program that may or may not be executed, depending on the We can also chain conditional statements together to allow the computer to choose from several courses of action. We wi explore this using nested af-else statements as a switch stalement
