C# | Remove all objects from the Stack
Stack represents a last-in, first out collection of object. It is used when you need a last-in, first-out access to items. When you add an item in the list, it is called pushing the item and when you remove it, it is called popping the item. Stack<T>.Clear Method is used to Removes all objects from the Stack<T>. This method is an O(n) operation, where n is Count.
- The capacity of a Stack is the number of elements the Stack can hold. As elements are added to a Stack, the capacity is automatically increased as required through reallocation.
- If Count is less than the capacity of the stack, Push is an O(1) operation. If the capacity needs to be increased to accommodate the new element, Push becomes an O(n) operation, where n is Count. Pop is an O(1) operation.
- Stack accepts null as a valid value and allows duplicate elements.
public virtual void Clear();
Below given are some examples to understand the implementation in a better way.
Total number of elements in the Stack are : 6 Total number of elements in the Stack are : 0
Total number of elements in the Stack are : 5 Total number of elements in the Stack are : 0
