C# में Stack.Push () विधि का उपयोग स्टैक के शीर्ष पर किसी ऑब्जेक्ट को सम्मिलित करने के लिए किया जाता है।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public virtual void Push (object ob);
ऊपर, पैरामीटर ob वह वस्तु है जिसे स्टैक पर धकेलना है।
उदाहरण
आइए अब एक उदाहरण देखें -
using System;
using System.Collections;
public class Demo {
public static void Main() {
Stack stack = new Stack();
stack.Push(150);
stack.Push(300);
stack.Push(500);
stack.Push(750);
stack.Push(1000);
stack.Push(1250);
stack.Push(1500);
stack.Push(2000);
stack.Push(2500);
Console.WriteLine("Stack elements...");
foreach(int val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements = "+stack.Count);
stack.Push(3000);
stack.Push(3500);
stack.Push(4000);
Console.WriteLine("\nStack elements...updated");
foreach(int val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("\nCount of elements (updated) = "+stack.Count);
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("\nStack elements...cloned");
foreach(int val in stack2) {
Console.WriteLine(val);
}
Console.Write("Count of elements in cloned stack(updated) = "+stack2.Count);
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Stack elements... 2500 2000 1500 1250 1000 750 500 300 150 Count of elements = 9 Stack elements...updated 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 12 Stack elements...cloned 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements in cloned stack(updated) = 12
उदाहरण
आइए अब एक और उदाहरण देखें -
using System;
using System.Collections;
public class Demo {
public static void Main() {
Stack stack = new Stack();
stack.Push("Inspiron");
stack.Push("Alienware");
stack.Push("Projectors");
stack.Push("Monitors");
stack.Push("XPS");
stack.Push("Laptop");
stack.Push("Notebook");
Console.WriteLine("Stack elements...");
foreach(string val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements = "+stack.Count);
stack.Push("Ultrabook");
stack.Push("Cameras");
stack.Push("Keyboards");
Console.WriteLine("\nStack elements...updated");
foreach(string val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("\nCount of elements (updated) = "+stack.Count);
stack.Clear();
Console.Write("Count of elements (updated) = "+stack.Count);
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Stack elements... Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements = 7 Stack elements...updated Keyboards Cameras Ultrabook Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10 Count of elements (updated) = 0
