Hii friends

welcome! Please read the pinned message :)

What logic solve this problem

You have to write two programs to transform input array into output array. Part 1 Input Array :  2,4,8,5,12,15,6,10,7,30,25,43,46,45,21 Output Array :  2,4,8, 12, 6, 7, 43,46,21, 5,15,10,30,25,45  

Thanks

🌺👍

Welcome bro

Hey guys do I need to finish oop concepts of C++ to learn how to use unreal engine?

You really need a deep understanding of: 1- Programming 2- and The C++ Programming Language 3- and various programming technique and patterns. 4- and more based on what you want to do. your question is not clear.

Well I can't get any more clear than this. I tried to check my answer and people usually answer based on opinion so I needed some actual advice

Answer this question

Read books, practice and watch videos to learn programming.

That I will

You have to write two programs to transform input array into output array. Part 1 Input Array :  2,4,8,5,12,15,6,10,7,30,25,43,46,45,21 Output Array :  2,4,8, 12, 6, 7, 43,46,21, 5,15,10,30,25,45  

Hey man wouldn't this need you to change the number based on index number?

How can solve

How can solve

Well you do the usual and then you just got to access each element of the array by using its index number

That doesn't make any logical sense.

What?

You know this answer

constexpr auto length = 3ULL std::array<int, length> array = {1, 2, 3}; std::for_each(array.begin(), array.end(), [](auto& element) { /* do your operation */ }); for(auto const element: array) { std::cout << element << ", "; } std::cout << std::endl;

What?

Sorry, wrong replay.

Sorry, wrong replay.

Do you see his output numbers don't match input numbers?

Yes I know

Yes I know

He is asking for logic behind it... you're giving him how to print an array.

Well if you want a really manual method you could use the fact that you can access the numbers like for example....... int num[] = { 2 , 3 , 4 , 5 }

I have don't understand this program

Do you see his output numbers don't match input numbers?

And the /* ... */ section is exactly for that.

I have don't understand this program

Learn English please

Sorry

It's my mistake

Well if you want a really manual method you could use the fact that you can access the numbers like for example....... int num[] = { 2 , 3 , 4 , 5 }

#include <iostream> using namespace std ; int main() { int num[] = { 2 , 3 , 4 , 5 } ; num[3]; num[3] = 8; cout << num[3] << endl ; return 0; }

And the /* ... */ section is exactly for that.

Yeah and he doesn't know the logic how these numbers converted.

#include <iostream> using namespace std ; int main() { int num[] = { 2 , 3 , 4 , 5 } ; num[3]; num[3] = 8; cout << num[3] << endl ; return 0; }

This is a rough idea but you could do it something like this.

Yeah and he doesn't know the logic how these numbers converted.

😂😂So i left him to think about it.

I've tried this before and i kind of did it like this

Hey guys do I need to finish oop concepts of C++ to learn how to use unreal engine?

For unreal in particular I would recommend you to do stuff with blueprints only first to learn how unreal classes relate to each other. Once you feel comfortable with blueprints, start to migrate blueprint classes to c++ classes one by one. You will learn quite a bit of the necessary c++ in the process and most of your blueprints knowledge will translate in some way to c++

Also note, for using unreal I would say it is a *must* to understand how blueprints work, so you will not be wasting time at all

bruh, this cant be a full question, you are probably missing the upper or lower half of the question...

Blueprints? I'm about to learn oop and my courses tell me about unreal engine a lot

I thought it might be related

Blueprints? I'm about to learn oop and my courses tell me about unreal engine a lot

I dont know your particular curriculum, but blueprints are the visual/scripting language used in unreal. Entire games can be (and some are) shipped without using c++ and only blueprints, but of course c++ is a lot more performant

Oh

My recommendations comes from someone who uses unreal for games, if you want to do other things you may need a different approach

Blueprints is like a programming language?

Yep, but completely visual with nodes

It is that way because artists and game designers need to program unreal as well

Yep, but completely visual with nodes

Well I'm not sure what visual or nodes are but I guess I'll get to that

It is that way because artists and game designers need to program unreal as well

Oh. So animators too

Exactly

Exactly

So someone with no C++ knowledge could just use blueprints. Okay but does it improve overall performance of my code if I use blueprints along with C++?

Yes. You could do your game entirely in blueprints, or entirely in cpp. Cpp being more performant but more tedious in many ways. Each has its pros and cons. In practice what happens is that the base systems that the game relies on are implemented in c++ and gameplay programmers, game designers, tech artists, animators, etc inherit the base c++ classes with blueprint classes to extend functionality

Thanks for the info

Quite more valuable than you think. All that most people talk about unreal engine is if it is better than unity and stuff

It's different, not better. You should choose an engine based on your particular needs

So thanks

You're welcome

i'm learning c++ but i'm not able to understand some fundamentals like bit manipulation. can you suggest a book for c++ fundamentals

Bit manipulation is not a C++ topic, I don't have suggestions for it sorry.

This is programming fundamentals, not c++

Any one know this answer

You have to write two programs to transform input array into output array. Part 1 Input Array :  2,4,8,5,12,15,6,10,7,30,25,43,46,45,21 Output Array :  2,4,8, 12, 6, 7, 43,46,21, 5,15,10,30,25,45   Part 2 Input Array :  2,4,8,5,12,15,6,10,7,30,25,43,46,45,21 Output Array :  2,4,8,21,12,46,6,43 ,7,30,25,10,15,45,5 IMPORTANT: Do not use duplicate or extra array, your program will be rejected if you use extra array. Output should be same array not print statement. Please note pattern of output.

what is happening in this array int a[10]={1,2,3,[8]=5,4}; ?

After printing all values, it is printing 1230000054

Is it [8] = a[5]? Then how?

Is it [8] = a[5]? Then how?

Me too, i really want to those things become part of standard.

#include <iostream> using namespace std; int main() { int a=1025; int *p=&a; char *po; po=(char*)p; cout<<p<<po<<*po; // Now firstly I printed 'p' which gives "adress of a" //And after that when I tried printinf "po" and "*po" the compiler does not print anything in c++, but in c it will work. Why so? }

Please tell
