Like how? is there series of questions? To solve them and learn?

Have you coded anything? in any language?

Java little not too much

Simple programs like String Reverse and Fibonacci something like that

Java little not too much

How did you learn to program in java?

It took 3 years

But I want to learn something in some weeks

But I want to learn something in some weeks

Try php

Well C/C++ will take more time than that

are you really know this language?

Php very slow🐌🐌

no)

Dave Plummer is a retired senior Microsoft's NT kernel programmer and he said that finally he is getting good at programming on C/C++

Why

well OOP, well site parsing, well cli with database access, 0 dependencies

Look guy's

According to tiobe index php stand 8 place

@a_semicolon just like you learn Java: Read books, watch videotutorials and code projects in the language you want to learn

@a_semicolon just like you learn Java: Read books, watch videotutorials and code projects in the language you want to learn

And java cover whole market

@a_semicolon just like you learn Java: Read books, watch videotutorials and code projects in the language you want to learn

You learnt C++ right?

When use java and springboot

@a_semicolon just like you learn Java: Read books, watch videotutorials and code projects in the language you want to learn

May take time but if you are disciplined, at the end you'll see the results

Bjarne Stroustrup said he knows C++ 8/10

You learnt C++ right?

I am still learning C/C++

I am still learning C/C++

But atleast you know something right?

Yeah for sure

May I know why you started learning it and where are you using it currently?

i think 1.5 year (for newbie in programming) it's enough to work as a Junior C++ developer

i think 1.5 year (for newbie in programming) it's enough to work as a Junior C++ developer

Well I'm not a newbie I know basics of programming

May I know why you started learning it and where are you using it currently?

Cuz i wanted to develop videogames. I develop applications for POS.

Well I'm not a newbie I know basics of programming

what do you mean by basis?

i think 1.5 year (for newbie in programming) it's enough to work as a Junior C++ developer

Agree

Cuz i wanted to develop videogames. I develop applications for POS.

What's POS?

Most famous one. Try to guess

what do you mean by basis?

Actually I'm working as QA in an Automation Team so I'm using Java to automate web applications using Selenium, there I'm using OOP concepts and other things also

Most famous one. Try to guess

Play Station?

Play Station?

What? no. POS stands for Point of Sale

What? no. POS stands for Point of Sale

Oh I thought it's related to some OS

What? no. POS stands for Point of Sale

Devices used to process electronic transactions, using credit cards

pc with touch display without keyboard and mouse

pc with touch display without keyboard and mouse

Oh cool

pc with touch display without keyboard and mouse

That's more like a Kiosk

So what kind of projects you did bro?

POS usually have IC Chip reader and a Magnetic stripe reader

So what kind of projects you did bro?

Maintenance and develop new features for POS applications

Maintenance and develop new features for POS applications

No I mean during your learning?

Some "games" like a Conway's game of life and an Asteriod like game

But you did that after completing the language like 80% or something right?

But you did that after completing the language like 80% or something right?

After i learn the necessary stuff to code it.

After i learn the necessary stuff to code it.

So during learning that necessary stuff did you code something ot just keep reading the theory?

You cannot expect to learn every feature of the language to start using it.

I read somewhere in a programming book that "No one never learn programming by just reading"

Yes I know bro

But I'm not sure why should I learn it😅

Guys lm new to programming can you assist

On the above assignment

void insertathead(node* &head, int val){ node* p = new node(val); head->prev=p; p->next=head; head=p; return; }

can anyone help in this above progarm of adding a node in the head of a doubly linked list

class node{ public: int data; node* prev; node* next; node(int val){ data=val; prev=NULL; next=NULL; } }; this is the node class

can anyone help in this above progarm of adding a node in the head of a doubly linked list

Not sure what you are asking for. To add a node to your head, you just need to call the function you already provided
