new uses std::allocator

And it can allocate through anything

class A has a map of <unsigned int, void*> which maps id with corresponding B<T>. class B is a template class and inherits from A. it has a private member id. now i need a function which takes an id and returns a pointer to B<T>. so i can do something like auto b = getById(1); i am unable to write such a function. pls suggest . thankyou

sorry my bad. message edited.

no

yes :/

not a singleton class .poor design i know

Hi! I try to launch a small project in the debug mode It has a grid class - matrix of char When i run the project in the debug mode execution crashes with exception Grid::operator [][]: (1095343392, 285277072) is outside of valid range []

i am pretty sure that i didn't call any out of bond member of Grid cause the call to the grid elements in the project is done only inside a loop

for r< grid.heigth() for c < grid.width()

Well it seems that you caught ub.

And it literally can be anything

well the debugger crashes. when i launch the project it works

but the debugger crashes

in release mode - works. debug mode - out of bonds exception

That's just classic UB action right here.

Yeah like positive integers. Let's say upto 10

so not "number" but fib(n) right...

😂😂😂

so not "number" but fib(n) right...

I don't know. I'm just a beginner. I only know basic. So I have assignment to make program to find factorial of a number using only if statement.

well mathematics is a prerequisments for programming... you won't get far without mathematics

oh factorial ... my bad... i am doing multiple things at once c:

the same thing applies to factorials as well

I don't know. I'm just a beginner. I only know basic. So I have assignment to make program to find factorial of a number using only if statement.

google how to find factorial or what does it mean by factorial of a number

no... not at all... i am not talking about addition and multiplication.... the mathematics logic is more important than some addition... i mean... addition is not enough

well mathematics is a prerequisments for programming... you won't get far without mathematics

Depends. Web devs dont really need math unles they use openGL web

i thought we are talking about basics and about c/c++.... but.... whatever...

Hey guys, would anyone be willing to take a look at my source code and help me understand using call-by-value? I have an assignment due tomorrow at 9am so I cannot reach out to the professor at this time.

send it in

my apologies everyone. I'm new to the chat and didn't know any better guys

Ok so after reading the rules it appears that it is appropriate to post screenshots of my source code and ask for help in the main chat as long as I've taken the effort to try and figure out the answer on my own and through using other resources like search engines and Stackoverflow(which I have done already)?

I think he just meant that you should send the source code in a text format rather than a screenshot

ah gotcha

@admin

I know when using the input values of 2 and 10 I should return the side area of a cyclinder to be 19.4778 but I don't fully grasp the concept of call-by-value as I just learned about it this week and I cannot determine where the mistake is. Any help or advice would be appreciated

sorry by mistake
