3. Logical Operators, Operator, Meaning, Example, AND, A<B AND B<C, Result Is True if both A< B and, B<Care true else false, OR, A<B OR B<C, Result is True if either A<B or, B<Care true else false, NOT, NOT (A> B), Result is True if A>B is false, else true, Every activity has a sequence of steps that need to be, followed., • The steps written in an order to solve a particular problem, is called an algorithm,, The steps written in algorithms can be represented, diagrammatically with the help of a flowchart., A flowchart is a diagram that represents a set of, To, Sum, Up!, instructions., An oval shape indicates the start or end of the process., A parallelogram indicates data input or output for a, process., Exercise Corner, A. Tick (/) the correct option:, that need to be, 1. Every activity has a sequence of, followed., b. stairs, c. rounds, a. steps, 2. A, uses some special symbols., a. algorithms, b. presentation, c. flowchart, 25, 1
