for my style, I changed some things:
Code: Select all
for(unsigned i = 0; i < temps.size(); ++i)
sum += temps[i];
just pointing out that you can shorten "unsigned int" to "unsigned". I changed the style so my head wouldn't explode.

I actualy prefer:
Code: Select all
for (unsigned int i=0;i<temps.size();++i)
{
sum+= temps[i];
}
I just didn't want to bitch about it

Yeah and what happens if you type in
unsigned x = 0.5f; ?
I guess, I'll try that out later.

The program will have to do a runtime conversion, making x = 0.

Actually, it doesn't return an unsigned int. It returns a size_type (vector::size_type, super-specifically). Which happens to be an unsigned int. But "it might not be later." The same way that NULL "might not be 0 later."
Also, I don't write size_type either, but I think your loop
should (technically, again) look like this:
Code: Select all
for (vector::size_type i = 0;i < myVector.size();++i)
But... that's slow (you're recalculating the size every time!). So you shouldn't be doing that, anyway. You should
at least be doing this:
Code: Select all
const unsigned int max = myVector.size();
for (unsigned int i = 0; i < max;++i)
But this is faster:
Code: Select all
for (vector<myVecType>::iterator i = myVector.begin(); i != myVector.end();++i)
Where myVector is defined as
And you can probably go even farther and (I don't go this far) :
Code: Select all
const vector<myVecType>::iterator max = myVector.end();
for (vector<myVecType>::iterator i = myVector.begin(); i != max; ++i)

ok this does work and sorry again schools been loading on the homework and I have to make money now and then too so for the lateness my appologies.
Like I said earliar this does work but when all nubers are written in a box pops up with a big explination point and says debug assertion failed.
why?
ps.If it matters I am using microsft visual c++ express edition.

you should change the post name if possible, because the abbreviation you're looking for it etc. NOT ect.
ect. makes it look like your trying to say eccetera, exetera, ecetera... but, the phrase Et Cetera, is what it should stand for, so etc. is correct. It is Latin it means "And So On(ward)"
thats all : D

first off i will enter the data and it will say the average and median tempurature and then the debug asertion warning thing.
second thank you for cerrecting me im all for that.

Okay, so what comes after the median temperature line?

I think nothing but, then again their might be some spaces in there.Anyway pretty much nothing comes after the median tempurature line other than the warning that pops up.
and thank you

I am not sure if this is what you meant but it could be between line 19 and line 24.

It's like trying to pull teeth from a chicken.
Look, this is all the source of yours I found in this thread:
Code: Select all
using namespace std;
int main()
{
vector<double>temps;
double temp;
while(cin>>temp)
temp.push_back(temp);
double sum=0;
for (int i=0; i<temps.size();++i)sum+= temps[i];
cout<<"average temurature: "<<sum/temps.size()<<endl;
sort(temps.begin(),temps.end());
cout<<"medean temurature: "<<temps[temps.size()/2]<<endl;
What comes after the last line here? It seems like there wouldn't be an error in this code.
