[Dev-C++] STL Vector

[David M. <ci...@ya...>]

This may sound really stupid but here goes.

I have a vector of objects (STL vector, just an arbritary
class). I have just pushed an object onto the end of this
vector. I want the index (the number I put in [] to access
the object) of the object I pushed onto the back. How would
I do so? (vector.size()?, or .end())

vector.end() returns the object contained in the last position of vector.=

If you want the index, you should use vector.size()-1

The straight way to do it is   myarray[myarray.size()-1]


Another way to do with [] is:  myarray[myarray.end()-myarray.begin()-1]



Or you can access it with iterator:

E.g.:  vector<int>::iterator p;

//...

p=myarray.end()-1;

*p=7;
