In today’s session, we will explore the fundamental concept of Logical Operators. These operators are essential for evaluating the complex logic required in real-world programming scenarios. To ensure a clear understanding, we will begin with an analysis of Truth Tables, followed by practical code examples. Stay focused, as mastering these tools is a vital step in your development journey. There are three logical operators and, or, not. First we understand truth tables. Lets start with and operator. Think of the and operator as a requirement for both sides. If you tell someone, 'I have a car and a bike,' your statement is only honest if you actually have both. It’s the same in programming! The and operator only gives a True result if both sides of the expression are True. By examining the Truth Table, we can see this clearly: x and y is True only when both variables are True. Just remember: if it’s an and operation, both must be True to get a True output. take an example. check the code given in the video. in the code first xgty executes. its a relational operator after execution it results in true. after that zgtx executes and results in true. now take a look true and true means and operator result in true finally we get a=true. this is how we use and logical operator to check two or more conditions. Next, let’s examine the logical or operator. Unlike the 'and' operator, the or operator evaluates to True if at least one of the conditions is true. By reviewing the Truth Table, you will notice that the expression only returns False when both operands are false. Let’s analyze a practical code example to see this logic in action. Let’s examine the Logical NOT operator. This operator functions as a complement, meaning it reverses the logical state of its operand. For example, if a variable x is True, applying not x results in False. Conversely, if x is False, not x evaluates to True. As you can see in the Truth Table, the output is always the opposite of the input. An essential technical point to remember from our previous discussions is that the not operator is a unary operator, as it operates on a single variable rather than comparing two. visit our website at www.wisdomers.in for quizzes and projects
