Lesson 15. Fundamentals of the C# Language (3)

Objective: Provides a comprehensive understanding of the principles of working with arrays as object data structures that integrate the methods of the .NET platform base classes for efficient information processing. At the lowest level of Knowledge/Remembering, the student must define the concept of an array as a reference-type data type, name the base class System.Array from which arrays inherit their properties, and list the main ways to initialize one-dimensional and multidimensional arrays. The Understanding level requires the student to explain the logic of memory allocation for arrays in the Heap area using the new operator, interpret the features of accessing elements by index, starting from zero, and formulate the difference between rectangular and jagged multidimensional arrays. At the Applying level, the student must demonstrate the ability to use the foreach loop to iterate through array elements, use the Length property to control array boundaries, and solve a practical problem of copying an array using the Clone() method. The fourth level, Analyzing, requires the student to analyze the advantages and limitations of using the Array.Sort(), Array.Reverse(), and Array.Clear() methods when manipulating data, distinguish the behavior of an address variable and the array object itself in memory, and compare different types of multidimensional arrays in terms of their ease of use. At the Evaluating level, it is necessary to justify the choice of a specific method of the System.Array class to optimize sorting or data clearing algorithms, criticize attempts to access array elements outside its boundaries, and evaluate the role of the object-oriented implementation of arrays in C# to ensure security and development flexibility. At the highest level of Creating, the student must develop (plan) an architecture for processing large data sets using multidimensional structures, and design (create) a software module that integrates several standard methods of the Array class to implement a holistic array transformation algorithm.
