Any error messages？show how you're trying to run it

bash: ./kral: Permission denied Like this

Hi everyone.I have an issue about termux When i make an executable file using clang -o it creates a program but I can't run it.How to solve this problem?

I'm new here How do I start c++

I'm new here How do I start c++

What's the permissions on it?

It is Android lmao

Yes. What are the permissions on the file?

Only memory here and it is allowed

Only memory here and it is allowed

What is allowed?

You mean app permissions?

The binary that you are trying to run

Idk but it is in telephone memory not sd or external card

bash: ./kral: Permission denied Like this

chmod +x kral && ./kral

Still the same error

Can I create an application using C++

Can you explain how please

Can you explain how please

I just have a little concepts in programming

Fine,, thank you

What would be the best approach to implement the following: You have to take a whole number input for the number of elements (N) in an integer array, the number of inputs (not pre-specified) given to be entered as elements of the array can be greater or less than N and are separated by a newline character. If the number of inputs isn't the same as N, then print "Wrong Input" otherwise print the array. I'm not sure how I can check for the number of inputs separated by a newline character without causing the program to hault when too few inputs have been entered. If I check for inputs beyond N number of inputs and the number of inputs turns out to be less than that the program that keeps waiting for that input forever. Is there a way to like check for extra inputs but if there's not there then to make the program continue executing? Program should ideally not use any special libraries as the inputs will be coming from standard io stream.

One thing you can do is to wait for an empty string (when prompted, the user presses enter instead of entering the next number, and then you count that as the end of the sequence)

Yeah that's the thing, I can't control the user. The input would be coming from automated tests.

Assuming it is C++ you're talking about

Ah, well, then I guess your stream will be closed I don't remember how to check for that properly (I remember it is tricky) but it is basically similar to reading from a file stream. It either related to std::cin.eof() or to std::getline(std::cin, line) returning false

My Ws I see that you address elements of an array, but your array pointer is nullptr (basically telling that there's no array to be addressed). You can create an array on the stack and address into it. int myArrayOnStack[200]; array_c = &myArrayOnStack; Or you can allocate an array dynamically, but then you need to make sure to deallocate it after. In C: https://www.geeksforgeeks.org/dynamic-memory-allocation-in-c-using-malloc-calloc-free-and-realloc/ In C++: https://www.geeksforgeeks.org/how-to-dynamically-allocate-an-array-in-cpp/ Also in C++ there's std::vector that would take care of memory allocations for you and will let you concentrate more on the app logic. Specifically in this case when you may not know the size that you need in advance

so i cant create undefiend size array?

You can allocate a specific amount of memory (memory for a specific amount of elements), then when you reach that limit and need more, you would need to allocate more memory, copy your data to the new memory and then deallocate the old memory (or use realloc in C). It is what std::vector does under the hood, whenever you push_back into a std::vector, it checks whether there's enough memory preallocated to fit one more element, and if there's not then it increases the size of the buffer to fit more elements (usually grows x2 of the previous size). That's also why iterators to std::vector can be invalidated on insertion/push_back, because if the growth of the buffer happens, then an old iterator would point to some old memory (that is already deallocated), meanwhile the element would be already in the memory of the new bigger buffer.
