bhai hope you remember me....i came back to your channel after many i want to remind you that I told you One Day this channels subscriber wud be said 1M is toooo big, but now see very soon this channel is going to achieve that...congratulations

[amritmoydas]

Sir ek request hai aapse, aap Computer system architecture ke upar full course ke video banao na me wait karunga, bohot benefit hota.

Pro tip
use pointer to pointer Nodes in functions enqueue(struct Node **f, struct Node **r, int val) and dequeue(struct Node **f) ; so that pointers you move inside function actually reflect changes in driver code

why this video has so much dislikes..shame on u those who are disliking this great content vedios ..if u cant do like then plz dont do dislike also...

[aryangupta]

Plz plz plz complete the syllabus of data structures and algorithm.
I have completed your python, git, web development complete playlist.
I need ds and algo for my clg syllabus.
Plz complete the syllabus.
Humble request

Sir you really deserve 1 billion subscribers
I know you work so hard to put multiple vidoes daily.
You are the God of Coding.
Because you know everything from a-z.
There is a playlist on almost everything.
Hats off to you Sir🙏🙏

Hats off to u Sir

Mind Blowing Class, Thank you for the tutorial <3

Queue implementation using Classes:
#include<bits/stdc++.h>
using namespace std;

class Node{//Created a Class Node same as Struct;
public:
int data;
Node* next;
};
Node *f; // Global uses and avoid return type;
Node *r;

class Queue{ // specified class for Queue for code reuse;
public:
void Enqueue(int val);
void Dequeue();
void Display(Node* ptr);
};
int main(){
Queue q;
//Enqueue;
q.Enqueue(20);
q.Enqueue(30);
q.Enqueue(40);
q.Display(f);
//Dequeue;
q.Dequeue();
q.Dequeue();
q.Display(f);
return 0;
}

void Queue::Enqueue(int val){
Node* n = (class Node*)malloc(sizeof(class Node));
if( n == NULL) cout<<"Queue Is Full.\n";
else{
n->data = val;
n->next = NULL;
if(f == NULL) f = r = n;
else{
r->next = n;
r = n;
}
cout<<val<<" new Node has been added.\n";
}
}

void Queue::Display(Node* ptr){
cout<<"Total Queue is : ";
while(ptr != NULL){
cout<<" "<<ptr->data;
ptr = ptr->next;
}
}

void Queue::Dequeue(){
if(f == NULL) cout<<"Queue is Empty.\n";
else{
int val = -1;
Node *ptr = f;
f = f->next;
val = ptr->data;
free(ptr);
cout<<"\n"<<val<<" has been Removed.\n";
}
}
