ReList.cs

Description

ReList.cs defines a generic list implementation ReList<T> that mimics some functionalities of List<T> in C#. It includes basic operations like adding, removing, indexing, cloning, and equality comparison.

Features

• Generic Type: Supports storing elements of any type T.
• Basic Operations: Includes Add, Remove, Clear, Contains, CopyTo, IndexOf, Insert, and RemoveAt.
• Equality: Implements IEquatable for comparing lists.
• Cloning: Implements ICloneable to create a deep copy of the list.
• Iteration: Implements IEnumerable<T> for iteration using foreach.

Methods

• Add(T item): Adds an item to the end of the list.
• Clear(): Clears all items from the list.
• Contains(T item): Checks if the list contains a specific item.
• CopyTo(T[] array, int arrayIndex): Copies the elements of the list to an array starting at a specific index.
• IndexOf(T item): Returns the index of the first occurrence of a specific item.
• Insert(int index, T item): Inserts an item at the specified index.
• Remove(T item): Removes the first occurrence of a specific item from the list.
• RemoveAt(int index): Removes the item at the specified index.
• Equals(ReList<T> other): Compares two lists for equality based on their elements.
• Clone(): Creates a deep copy of the list.
• GetEnumerator(): Returns an enumerator that iterates through the list.

Additional Method

• PrintReList(): Prints all elements of the list to the console.

Program.cs

Description

Program.cs demonstrates the usage of ReList<T> with integer elements. It showcases basic operations, cloning, equality comparison, and iteration using foreach.

Example

ReList<int> list1 = new ReList<int>();
list1.Add(1);
list1.Add(2);
list1.Add(3);

Console.WriteLine("List1:");
list1.PrintReList();

ReList<int> list2 = new ReList<int>();
list2.Add(1);
list2.Add(2);
list2.Add(3);

Console.WriteLine("List2:");
list2.PrintReList();

bool areEqual = list1.Equals(list2);
Console.WriteLine($"Are List1 and List2 equal? {areEqual}");

ReList<int> list3 = (ReList<int>)list1.Clone();

Console.WriteLine("List3 (cloned from List1):");
list3.PrintReList();

list3.Add(4);
Console.WriteLine("List3 after adding an element:");
list3.PrintReList();

areEqual = list1.Equals(list3);
Console.WriteLine($"Are List1 and List3 still equal? {areEqual}");

Console.WriteLine("---------");
foreach (var item in list3)
{
    Console.WriteLine(item);
}

Output

List1:
1 2 3 
List2:
1 2 3 
Are List1 and List2 equal? True
List3 (cloned from List1):
1 2 3 
List3 after adding an element:
1 2 3 4 
Are List1 and List3 still equal? False
---------
1
2
3
4

Conclusion

This project provides a custom generic list implementation (ReList<T>) with fundamental list operations and demonstrates its usage through a sample program. It can be utilized as a learning resource or integrated into projects requiring custom list functionalities.
