[Dev-C++] vector

[Lloyd <ll...@cd...>]

Hi,
 How can I resize a vector (in STL) and initialize "all" the nodes with
a particular value?

Thanks and regards,
  Lloyd

You can use the resize() like this:

myvector.resize(10);
for(int i=0;i<10;i++)
myvector[i] = 0;

More details on vectors can be found here:
http://www.cppreference.com/cppvector/index.html

regards,
Rory.

Thank you Rory, But I would like to know which one would be better (in
execution)
 
as you said

> myvector.resize(10);
> for(int i=0;i<10;i++)
> myvector[i] = 0;

or

myvector.clear()
for(int i=0;i<10;i++)
 myvector.push_back(0);

Thanks,
 Lloyd

I'm afraid I can't say. Perhaps someone else on the list might be able 
to tell us. For what it's worth I've used both methods and I didn't 
notice any great difference between the two in terms of execution.
