Can any one help me

Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is. These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot? If you have a question ask it directly. You are more likely to get a response that way.

No such thing, don't use C++ for GUI

Why not? For example, Qt, you don't recommend to use it at all?

No. For very simple GUIs I can tolerate ImGui.

But C++ is horrible for UI stuff. I prefer Flutter

hello!, in this part of code there are some error? because the switch Always goes to default

switch(tp) { case 1: { v = V1; type = "la coca cola"; }

case 2: { v = V2; type = "il panino con il prosciutto"; } case 3: { v = V3; type = "la torta con frutta"; }

case 4: { v = V4; type = "la pizza"; } default: {std::cout<<"Questa selezione non \x8a valida!"<<std::endl;} }

hello!, in this part of code there are some error? because the switch Always goes to default

you need to break; at the end of each case

case 4: { v = V4; type = "la pizza"; } default: {std::cout<<"Questa selezione non \x8a valida!"<<std::endl;} }

at first, add break to every case

right!, sorry

Hey guys could you help me where can I practice my problem solving skills in C

I have exams on that

What do you need help with

I would like to practice my c skills

Seems like i cant send links here

just google "practice c"

try leetcode

try leetcode

Yes do that

case 2: { v = V2; type = "il panino con il prosciutto"; } case 3: { v = V3; type = "la torta con frutta"; }

Non si vede che sei italiano propio no Use chat gpt for this kind of issues, way faster and easy, avoiding to wait for someone to answer. At least for syntax related problems, even if sometimes it is a good solution for logic related problems

Heya :) PM me if you have any questions on how to use me!

No I have no question now if when I have so I will ask

Sorry i didn't notice it was a syntax error, I thought it was a logic error that I made inside the function. This community is for learning not for offending 😐. Maturity is the first rule and even c++ doesn't teach it

Does deque provide better performance than vector in terms of insert at the back?

Does deque provide better performance than vector in terms of insert at the back?

Depends, deque will allocate more times if you insert many elements compared to a vector. But a vector will move all existing elements once it needs to reallocate. So I assume that inserting at the end of a deque can be faster than at the end of a vector for types that are heavy to move or if there are really a lot of elements in the container. In other cases I assume that vector will be faster on average. You can try to measure this (e.g. with quickbench), to get more precise values, to see at which point one becomes faster than the other.

These are ways you can improve the odds of someone wanting to help you. Be considerate when posting questions. • Use a search engine to check if anyone else had the same question as yours before asking. Stackoverflow is your friend. • Be straight to the point (do not ask to ask.) • Be specific, include as many details as you can. • Show what you've tried to solve the problem • We don't care if anything is "urgent" or "important" - wait patiently for someone to reply. • In addition, please check this site to learn how to ask questions in a public forum. It's good style to limit the amount of messages you send to a public forum; put effort into 1 message, rather than sending many of them, and edit messages to fix errors or to include more information.

There are two ways to insert to the back of a vector: "emplace_back" and "push_back", "emplace_back" is usually considered to be faster because it constructs the element in-place. I am not sure if deque has a in-place method for "pushing".

It has emplace_back as well. Also emplace_back is faster only if the object is not already constructed (meaning that you provide the arguments to construct it and not an existing object of the same type), otherwise it will just invoke the same copy/move constructor as push_back would.

You mean the program compiles but you get an error when trying to run it？

hello im trying to make a math tutor program to exercise and have some issues i want to make a case where it generate random equatio s=ns with operators

is it ok if i send my code?

its c++

im having trouble making it so basdically here is the menu i want from it 1] Addition only 2] Subtraction only 3] Multiplication only 4] Integer Division only 5] Real Division only 6] Modulo only 7] Addition and subtractions 8] Addition, subtraction and multiplication 9] Addition, subtraction, multiplication, and int division 10] All operators 11] End program i need help with 7-10 i did 1 to 6 but i want help to make 7-10 please

i hope i was able to properly describe the problem

if you choose 7 for example, then the program ask you how many questions you want and lets say you asked for 5, its suppsoe to generate 5 questions with either addition or substraction, but the operator for each question will be random between both

rand with modulo I guess?

If random number is odd is addition, else subtraction

can i ask something other than c++

Offtopic discussions should be done in the C/C++ Offtopic group. Please take your discussion/questions there.

Hi, why standard can't just stricly define that enum underlying type should be for example int? What is the point that compliers can choose which integer type to use under enum? This creates many ambiguous situations

I don't really understand this about you. But for my simple sites I use PHP

can i ask something other than c++

No lol

You better google it

you could write your backend by C++

Hi I have query in c++ I have a double number suppose 1.45678384 i want that double takes only four digits after decimal number what is the methods

how to set entire boolean array to have false value in declaration ? or the entire array is false by default ?

I thought "biset" was set to false by default.

i dont understand, can you give code example pls ?

You can try "bitset<n> bs", and try to cout to see if the bits are set to 0

Hi I have query in c++ I have a double number suppose 1.45678384 i want that double takes only four digits after decimal number what is the methods

normally = %lf 4 digits = %.4lf

Also you can try vector<bool> v(n, false);
