Can anybody suggest good books to learn basic c n c++?

Read the pinned msg it is not that hard

BinaryByter

Read the pinned msg it is not that hard

Hi @spaceseks

Hello?

Amobeas can do that, and they are unicellular

klimi

wannabes?

Yh

when I initialize temporaryDerivative to 0, the unit tests don't pass anymore ;_;

BinaryByter

but when I keep it uninitialized, valgrind cries

klimi

idk even what valgrid is

klimi

im cool programmer

klimi

wait

klimi

im no programmer

klimi

then it doesnt matter ^^

BinaryByter

im cool programmer

❤️

BinaryByter

idk even what valgrid is

its a tool that tells you where you screw up

BinaryByter

when I initialize temporaryDerivative to 0, the unit tests don't pass anymore ;_;

@QNeko what could it be?

klimi

lol what the unconventional code

BinaryByter

lol what the unconventional code

what?

BinaryByter

I know, dat trainwrecking

BinaryByter

but for now it shall be fine

Dima

first for uses brackets while second not

BinaryByter

first for uses brackets while second not

I can only remove brackets for single line fors

BinaryByter

and its good practice to do so when possible

Dima

I know

Dima

even if one-line you should use brackets

Dima

lol

BinaryByter

even if one-line you should use brackets

no lol

Dima

rip

BinaryByter

anyway, let's stop bikeshedding lol

klimi

maxi help

BinaryByter

lol what the unconventional code

why does changing the value to 0.0 matter?

klimi

i forget one thing in c++

BinaryByter

maxi help

ok

klimi

how do i do reference to variable?

BinaryByter

i forget one thing in c++

what is it?

klimi

like

klimi

i want to do

klimi

somefunc(int x, int y)

BinaryByter

how do i do reference to variable?

int myVar; int* myPointer = &myVar;

klimi

but the x and y

klimi

i want to modify it

BinaryByter

somefunc(int x, int y)

dont use pointers for ints lol

klimi

i need it in function

klimi

like

klimi

to pass it from function

BinaryByter

bad practice ll

klimi

hm

klimi

ok

klimi

okay

klimi

i will do it

klimi

one by one

BinaryByter

bad practice ll

make two functions (or three functions) that each change the variable

klimi

ill do 2

BinaryByter

or make a class object

klimi

yeah

klimi

thanks

BinaryByter

that way you can return two at the same time

klimi

@linuxer4fun and is it ok to create temp int?

BinaryByter

Depends on what you do with them

BinaryByter

Show me code

Ludovic 'Archivist'

when I initialize temporaryDerivative to 0, the unit tests don't pass anymore ;_;

Try 0.5

Ludovic 'Archivist'

when I initialize temporaryDerivative to 0, the unit tests don't pass anymore ;_;

If it passes it means that the first value for temporaryDerivative was dependent on a non 0 variable

BinaryByter

Try 0.5

Why? And why does not initializing it work?

Ludovic 'Archivist'

Why? And why does not initializing it work?

Not initialized often means non 0

BinaryByter

Okay

BinaryByter

Mathematically, which value is best?

Ludovic 'Archivist'

Mathematically, which value is best?

0.5 is likely what you want

BinaryByter

Okay
