lol

hello guys!

could somebody help with the code to program a kind of 'battleship game' ?

in language c

anyone has the battleship code?

How so?

An battleship game?

anyone has the battleship code?

we've helped you in other group

we even gave you source code

start thinking instead of asking xD

and that source code has a lot of comments, so just read it

sry vms, i was trying to take the more resources as possible :(

the more the better

the more the better

google "battleship game in c"

hahahha not everyone has it

has what? google?

battleship game man

anyone has the battleship code?

No

even in google there are not so much good codes

even in google there are not so much good codes

yeah but

i mean good ones u know

even in google there are not so much good codes

Search it on github

Search it on github

xd

Someone knows an library kind of “vector” one, but better than it?

i mean good ones u know

how can you determine if it's good or not without even looking at the code? xD

who has told you that i had not look them homie

who has told you that i had not look them homie

tell me, which one is bad?

i ain´t saying that they´re bad, but there are with other different structures that i dont feel so much comfortable, bc i haven´t used them before.

you're loosing time

A good opportunity to learn something!

you're loosing time

🤨

🤨

start doing what they told you in the other group

make the two arrays and start from there

display the board, make a function to check the coords of a board, etc

alright

"kind of vector one"??? Do you mean std library?

Better in what?

I use the same namespace in separate cpp files(not separatint the namespace definition), then I got multiple definition of ..., why?

The circumstances is similar to http://www.cplusplus.com/forum/beginner/12458/

In this link seems like he's defining the i two times

The circumstances is similar to http://www.cplusplus.com/forum/beginner/12458/

namespace nn { int i = 5; }; Here's the error, this violates ODR

This should be divided into header and cpp Header with extern, cpp with nn::i = 5;

Or using inline if it's C++17

What if namepace nn{int i;}; is it correct?

Or just describ how to use the same namepace in multiple cpp file is ok

What if namepace nn{int i;}; is it correct?

AFAIK, it is still definition, so no. namespace { extern int i; }

Ok, thanks

Or just describ how to use the same namepace in multiple cpp file is ok

By the way, namespaces have nothing to do with the error. Without namespaces it would be the same.

Yep, I think the ordinary method is to use extern to declare a external variable, instead of namespace, which might often used for funtion name.

I just confused if it's used for definition while there are multiple files.

There's a rule of thumb: It you need a global variable that available in a header, use extern. And define it in cpp. If you need such a variable only for one cpp, use static.

I know how to use static and extern, though. Anyway, thanks for the advices.

Hello

Okay🙃

How about your programming knowledge..?

What?

What do you mean

hello. what is function recursion?

When you can the function within the function

Ass we can

what do you need

what?

learn language basics

Zero init

Use nullptr instead of 0. That makes code clearer.

basically the *things will point to nothing, correct?

It looks like homework to me

basically the *things will point to nothing, correct?

It is most of the time the same as 0. nullptr is an alias for an invalid pointer. Most systems use 0 as it is cheap to compare against 0. It is in theory possible to have other values for nullptr, another possible value is std::numeric_limits<intptr_t>::max()

In C++, using nullptr is always preferred as it is more readable

In C, it is advised to use the macro NULL

More like I hope there are no problems when doing something like Bar *array = new Bar [10];

Because in this case the default constructor would be called, am I correct?
