Topic 14

Lesson 14. Fundamentals of the C# Language (2)

Objective: Provides comprehensive mastery of program flow control tools from understanding branching syntax to the ability to design complex loop structures. At the lowest level of Knowledge/Remembering, the student must determine the purpose of the if, switch, while, do-while, for, and foreach statements, as well as list the keywords for controlling loop exit, such as break, continue, and goto. The next level of Understanding requires the student to explain the logic of execution of the full and abbreviated forms of the if construct, interpret the difference between loops with preconditions and postconditions, and formulate the features of the foreach loop when iterating over collections. The Applying level  requires the student to demonstrate the use of the switch operator for multivariate selection, apply the break and continue statements to change the standard loop execution logic, and solve a problem of finding the maximum of two numbers using branching. At the Analyzing level, the student must compare the effectiveness of using different types of loops to solve a specific problem, distinguish cases where labels and the goto operator are appropriate from situations where this worsens the code structure, and also analyze the impact of logical conditions on the number of iterations in a loop. At the Evaluating level, the student must justify the choice of the switch construct instead of multiple if-else to improve code readability, criticize the use of infinite loops without proper exit conditions, and assess the importance of structured programming to prevent the creation of confusing code. At the highest level, Creating, the student must develop (plan) an algorithm with nested loops and branches to process complex data structures, and design (create) a coherent program control logic that ensures the correct processing of all possible input states.
