yes and that pointer can't be null

And do you also know why some people says that it's better to use an object instance instead of a pointer

Because using reference more safe than pointer.

Yes

Because using reference more safe than pointer.

Wait

Because using reference more safe than pointer.

Do you also know what this code means Byte operator[](u32 address) const

reloading operator of index [ ]. In that case you getting byte by 32bit address

Yes ok

I understanded

I mean i know what is a static function but i remember i have seen using the static keyword also in functions that aren't in any class

And you don't know this

And you don't know this

What you mean? Give me example

I don't know like static void main()

google says that static function accessible only from file where that function declared

Yes thank you

How using reference is safer than pointer as a question?

Let's learn together

Okie

How using reference is safer than pointer as a question?

1. Inside a function if you receive a reference, you know for sure it's not null, so you can't do nullptr dereference 2. You can't accidentally change address instead of value 3. You can't accidentally be passing const pointer to a mutable value instead of pointer to a const value

Technically you can dereference a nullptr into a reference of course, but it's UB from that moment already, so no need to think about that inside the function

anyone here has used clang-query? I'm trying to define a matcher for const reference parameters. 🤔

and isConstQualified does not work since the reference is not directly const, but the const only applies to the value the reference is refering to

Thanks nice information Can change address We can’t change address of variable according to me

what does ?(question mark) operator do in c++

what does ?(question mark) operator do in c++

Ternary operator

Ternary operator

Elaborate

<condition>?<true>:<false>

if condituon is true, it will evaluate to <true>. Otherwise to <false>

example: int a = 2>3?4:5;

a will be set to 5

Amazing now I understand bro

thank you all so much

nice🔥

Sure, no worries. I'm thinking about making a playlist on youtube about C++. Would anyone here watch it? 🤔

ys

I'm a beginner in c programming somebody help me out to understand the basics so that I can apply in c++

Nice 🔥. I will think about what to cover and will link the playlist here once I uploaded the first video :3

Feel free to ask. Have limited time, but willing to help

Ofcourse do it I have no knowledge of c;+

im like on the job 12h a day when i include traveling time. Kinda bad

Who want to get C++ challenge

lol nice try to give out your assignment

Who want to get C++ challenge

Its about C++ metaprogramming

Just ask ^^. Might have time later

Like templates or old school preprocessor stuff?

Task: Write array/vector where you pass to parameters dimension of array. Like array<int,3> arr. 3 - dimension

Nice 🔥. I will think about what to cover and will link the playlist here once I uploaded the first video :3

It will help a long way men

You're blessed men

Mostly weekends and between 18:00 and 20:00 CET

I will check on this

No, templates

So its really C? Just using a C++ compiler to compile :p 😂

Task: Write array/vector where you pass to parameters dimension of array. Like array<int,3> arr. 3 - dimension

You need to do a basic reimplementation std::vector? 🤔

Sorry, im not 100% sure if i got the task

You need to do a basic reimplementation std::vector? 🤔

No. Universal template class that can turn to array with any dimension

One exception. Dimension not bigger than 3

Sorry, im not 100% sure if i got the task

I completed that task. That task helps understand a lot of C++ metaprogramming concepts

No. Universal template class that can turn to array with any dimension

Ah okay 👌

One exception. Dimension not bigger than 3

Is one allowed to use C++20 concepts?

Is one allowed to use C++20 concepts?

Yes

If yes, its pretty straight forward. but it got me thinking how I would do it without

Well ofc. you can always just static_assert(T < 4)

Well ofc. you can always just static_assert(T < 4)

I changed condition. You can make dimension larger than 3

I changed condition. You can make dimension larger than 3

I found other solution for (dim > 3)

Okay 🤔

can't you just: <std::integral T, typename Q> class template_array final { Q* values; public: template_array(): values{ malloc(sizeof(Q)*T)}{} ~template_array(){ free(values); } };

ofc. define some geters and seters

Also not good. since it always heap allocates.

but its simple

can't you just: <std::integral T, typename Q> class template_array final { Q* values; public: template_array(): values{ malloc(sizeof(Q)*T)}{} ~template_array(){ free(values); } };

What is Q mean

Just a template parameter

Hello! Why do I have this message? -narrowing conversion of ... from 'int' to 'float'. Is it because I store values in {} braces?

No, you need to write the value as a float literal: 1.0f for example

initializer lists dont allow implicit convertions

So how do I write it in here? And furthermore, why isnt there the same warning in the tutorial? I have done everything the same. LinkRunData{0, 0, LinkRun.width/12, LinkRun.height}

Not sure what it expects, but 0 is an integer literal, so ypu would need to write 0.0f instead

Hope that fixed it. Need to go :) good night folks ✌

#include <stdio.h> int factorial(int i); int main() { int f; printf("Program to do factors of a no.\n"); printf("Enter a no."); scanf("%d" ,&f); // Write C code here printf("the factorial of %d is %d", f ,factorial(f)); return 0; } int factorial(int i){ if (i ==1 || i==0){ return 1; } else{ return i* factorial(i-1); } }

Giving null or wrong output,any problem in code?
