help with arrays

[ResidentBiscuit]

Don't use dynamic memory.

Just use a vector.

std::vector<int> iVec;

Then just iVec.push_back(element); to add to it.

ill just show you the while loop please explain it to me from there

while (count > 4)
{
SetPixel(hdc, 0 + x[count], 0 + y[count], c);
count --;
}

[ResidentBiscuit]

What exactly are you trying to do? That just looks like your accessing a couple arrays.

[klay2]

I am it wont work im trying to have a variable declare a position in an array in a setpixel function

[ResidentBiscuit]

What error are you getting?

[klay2]

expression must have a pointer-to-object type

[ResidentBiscuit]

That doesn't sound like an error applying that snippet.

[klay2]

it is saying it about x[count]

[ResidentBiscuit]

And how is x declared?

[klay2]

int x [4];

[ResidentBiscuit]

Well first off your accessing memory outside of that array. From your loop, I assume count starts off >= 4?

[klay2]

what

So if it is out of range then access that item? doesn't make much sense what are you trying to do/accomplish?
