Much like we discussed in Flowcharts, in pseduocode, we can also nest our conditions. That means that within the body of one true statement, or the else, false statement, we can nest a whole new decision. A simple case is where we want to see if two things are both true, and we don’t know…
AS your applications become more complicated, you can expect your decisions to become more complicated. There are three ways this can happen. First, is a sequence of conditions, checking against the same variable. So in our last decision example, we mentioned how we cannot ask “What color is the shirt?” However, we might ask: “Is…
Conditional statements allow us to choose to run a portion of code, or not. It is dependent upon what they condition is, and if it is met. Conditions need resolved down to a boolean answer. That is one that can be described as a yes/no, or true/false, style of answer. Therefore “Is the shirt blue?”…
Sometimes you will need to have more complex conditions to determine what you need. This goes beyond having Boolean logic, but moves into finding a value in a series of values. This is where we might use a if else if series of code blocks, or a switch statement. If Else If Do you have…
You will find conditions in Java familiar if you are used to using boolean conditions in C/C++. However, noticed that I said boolean conditions. That is because Java wants boolean conditions, those that generate a true or false answer, instead of the C/C++ conditions which actually look for an integer value. Notice the following below…
A switch statement executes statements based upon the value of a variable. It is useful to replace a series of if statements, if the if statements are all looking for an equality value. The general form of this is below: Your variable must be an integer value, and must be enclosed in parentheses. The case…
If you want to do more complex decisions in C++ there are a couple of ways to accomplish this. We’ll look at three that are fairly common. Nested If Statements Inside of an if statement true block, or the else block for that matter, you can nest another if statement. This allows you to build…
C/C++ has a couple of different ways to perform selections. We’re going to start looking at some of these. As with most languages, C./C++ has a Boolean data type, called bool. This can be used directly with your conditions, or separately to store data. Relational Operators Since we will need to compare values, C/C++ gives…
