Hi, Excuse me everyone, I have a project on C++ about creating an application for a hotel system. I finished my project, but I have small errors that I could not solve. Can I send you the code and help me solve these errors?
You can send your code (e.g using pastebin or link to github), but you'll need to describe what kind of errors you mean (e.g. if it's a logical error, then what is the desired and current behaviors, if it's compilation error, then what is the error message, etc.)

You said a lot of advanced topic but you didn't even know how to get the plugin lol
I dont know how to compile it

hello, is there a way I can print out the vector without having to do a nested for loop? https://bpa.st/2IPO4

oh by the way, ignore my unused stack, I was gonna use that for later

Do you have the text of the errors?

You need to prefix ofstream and other C++ library classes with std:: or add using namespace std; somewhere before usage

For what I see just looking at it
🥀
Write a program that reads data into an array from a file “ input.dat”. The first value to be read from
the file is an integer that represents the number of floating-point values that will be stored in the float array
(assume that the array has a maximum of 100 elements). Compute the mean and standard deviation of the array
of data, then display on the screen and write into the output file “ output.dat” the difference between each data
value and the mean.

Write the code for the given output, you are not allowed to change the main.
(hint : something to do with constructor and destructor)
int main(){
cout << "Welcome to OOP";
return 0;
}
class A {
public:
A() { std::cout << “text” << std::endl; }
} A;

I am trying to read keyboard inputs using X11 Xlib, but I am getting the following error:
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 33 (X_GrabKey)
Serial number of failed request: 7

which is funny because the snippet I saw the guy says it works:

Use paper as favorite IDE? Sounds good.
How do you transfer and compile the code? Pencil?

To compile the code you can just use the voices of your head

I have a problem with std::string_view. I pass a string to function Foo1(string_view srv_v) which accepts string_view as a parameter than make 2 string_view vectors from this passed parameter and than I pass it again to another function Foo2(string_view str_v) which is inside the Foo1 and there string_view parameter lose its sequence. Somebody give me a hint, I dont change passed parameter in others places
Anonymous
also I don't need to store a data which contains string_view, so manipulate it to find some values from a map
Sulistyo
what menu? what selecting?
Menus are like class codes in the form of letters and numbers
And how do you compare it if the user has entered or retrieved the class code that is already available

I'm going to change my job from automation to embedded programming, i have an information that they will test me on C/Cpp to test my logical thinking, especially on OOP, via yours C/Cpp experience, could you guys suggest me some sample that they can ask me in the interview ? thanks

Definitely Classes and Structs, Namespaces and headers in my experience

It's better to send a code
And keep in mind that string view doesn't own the data it's like const string&

It seems to me we still get a memory leak if we use dynamic memory allocation when implementing stack data structures. Let's say the stack, which is implemented using an array, size is 5 and it is full. Lets call this array values[5]. If we want to push a new element, we create a new array in the memory with a double size of the old array (lets call it new_values[10]) and copy the values into the new array from the old array. After copying values, we deallocate the memory for the old array and point the "values" pointer to the same place in memory that the "new_values" is pointing to. If we deallocate the "values" at the end of our class implementation,in the destructor, do we get to delete the new_values and values pointers from the memory even though they are not pointing to anything anymore? It is just the pointers take some memory too. Can we delete them so the memory is fully freed or do they get deleted automatically if we delete the memory space they were pointing to?

Pointers allocated in the stack get deallocated automatically (i.e. the memory that the pointer occupies goes away). This is typically the case for pointers that are data members of your class and your class object is itself allocated on the stack. They are allocated on the stack. It is the memory that they point to which you should worry about.

Must of the time they ask you about easy to intermediate problems. They ask about the use of data structures and simple concepts like pointers or arrays. In my case they told me to use the heap and the stack in a basic problem and in cpp the use of the std library

My interview had questions like: Why do we use classes, or they give you big array containing a lot of data and tell you to convert it to struct (or vise versa) and headers don't really have much to offer, there could be questions about their properties maybe and yeah, oh btw I highly recommend watching "Data Structures" helps a lot in problem solving and memory management (if you want to use Pointers)
