#How to create array with size 1000000???

i can use vector if it will work
hollow wave
An array of what?
Making an array that large on the stack will almost certainly segfault yes, the stack is small
Either put it in static storage (global) or put it on the heap, vectors are a good idea
fluid hill
would vector with this big size work?

of structs

try it and see 
fluid hill
ok
bruh
memmove is not working the same for
vectors
memmove(parts + 1, parts, p * sizeof(parts[0])); //shift right by 1 snake parts pos
how to make it work for vector?

User vector.insert
its so slow...
fluid hill
If you’re repeatedly shifting over a million items lol
do u know way to make it faster??? maybe to use something instead of vector?? something that can insert something at beginning in faster way?
hollow wave
@fluid hill rethink your approach, why do you need to insert stuff at the beginning

Populate in the opposite direction?
Use a linked list?

insertion in a linked list is faster
that's the only reason why you'd ever want to use std::set

Consider linked lists, dequeues, and circular buffers
cosmic valley
is linked list faster?
No its slower, thats why I recommended it as a alternative to meet your speed requirements
languid vault
but yeah, in general data this big isn't ideal
hollow wave
Linked lists are almost always slower than alternatives
But if you really must insert at the beginning of a list of a million items it may very well be faster

ok, i need something even faster, it needs to end program in 32 seconds on 2GHz cpu...

Preallocate a huge buffer at the beginning of your program and use it
Did you consider other stuff might be eating up your cpu time
