What is a less command?

It's a command for browsing document. Users can navigate up and down freely in the stream of a document

That's one way to do it. From my experience this way produces less flashing than clearing the console and redrawing the scene.

Actually the reason for flashing is that you input x number of newlines/std::endls, which flush the output --> X is number of rows in terminal. X number of newlines in just a couple of milliseconds --> looks like something flashed

Therefore it's way better to use ncurses as it handles the flushing for you in multi-line (well you need to call the update function but that's it)

Well explained. Ncurses is simply magical

Hii

whats the best linux distro for developers

kali linux

thinking about getting linux because valgrind doesnt work on my mac

Ubuntu derivatives are pretty handy and configurable, good starting point. If you know linux well enough and can google, you might try arch

Theres no normal valgrind in homebrew/macports?

Lol

Lol

i either can get a virtualbox/linux , dual boot linux , or downgrade my mac os

Or patch valgrind

Or patch valgrind

what do you mean ?

what do you mean ?

Fork valgrind repo and try to setup it for your mac version

uf

Anyone know some good resources to learn C++?

patching valgrind may be very difficult

Fork valgrind repo and try to setup it for your mac version

according to stackoverflow its not compatible with anything higher then 10.12

patching valgrind may be very difficult

it's a very complex piece of software with a lot of hardcoded snippets of code

Im sure it is

i have 10.19

That was a joke

what distro of linux should i get fedora, ubuntu

I would try to setup a small virtualbox

Anyone know some good resources to learn C++?

learncpp.com

That was a joke

oh got it, I'm not good getting jokes

what distro of linux should i get fedora, ubuntu

if you are using virtualbox, debian, if you are setting up dual boot Ubuntu

Anyone know some good resources to learn C++?

#cppbookguide

if you are using virtualbox, debian, if you are setting up dual boot Ubuntu

i using a virtual box for now , is there any benefit to dual booting ?

it's faster, but I prefer vbox

Vm requires additional memory and cpu resources. If it doesnt matter, usability is the only issue

it's faster, but I prefer vbox

i need more harddrive space lol

I use vbox a lot, I develop crossplatform c/c++, and also many other languages, so I must setup many environments, I use it in combination with docker and kubernetes

do you have graphic enviroment or just console?

graphic environment

which one?

this should be enough

try it, later on you can tweak it

VDI, VHD, or VMDK

for hard disk file type

Isn't this ot

VDI, VHD, or VMDK

there is one that can be resized later but I don't remember it, I have vdi

Isn't this ot

yes ..

yes ..

Okay... No problem XD I just was curious

although it's very powerful for c/c++ crossplatform development, but I think it's offtopic anyway

it's very nice to develop visual studio c++ and debug with valgrind

at startup, the program lays down, who can look at what the problem is?

Is it possible to cast or transform std::vector into variadic arguments? I want to do this: template<typename T, typename... Args> bool foo(T f, Args... args) { return f(args...); } foo(f, a, b, c); Instead of : template<typename T> bool foo(T f, std::vector<int> args) { return f(args); } foo(f, some_vector);

I know how to do it with old standards, usually it is done by implementing all calls from 0 to N, but I'm sure newer standards have a better way of doing it, I'm a bit outdated in C++

i.e: foo_0() foo_1(f1) foo_2(f1, f2) ...

My main issue is, I need to call T f(int x1, int x2, ..., int xn) when I have a vector<int> in a generic way.

I know how to make a vector out of Args ... , but not other way around

maybe this helps

std::vector is a run-time beast. That is, it allocates its buffer on the heap and generally any manipulation is allowed during run-time. On the other hand variadic template "pealing" is done during compile time. Consequently, a std::vector and variadic templates are somewhat "disjoint". Thus, it's not possible to do what you want with a vector. *Feels bad man pepe*

Solved this problem by using template<typename T, typename size_t Size> double foo(T f, array<int, Size> args) { ... res = std::apply(f, args); ... } Maybe will be interesting for some people This way my f can be f(int x1, int x2, ... , int xn) Correct me if im wrong, haven't checked yet, but compiles and first tests seem promising :)

It can't like that You did something wrong

Lol

Why are you laughing?
