Deleting vector parts?

(WinXp, Borland C++ Free command line)
Ok, its come time I need to delete a nullified part of my vector.

Heres my code summed up:

Code:

int main() {
 vector <int> X;

 x.push_back(1);
 x.push_back(2);

 x[1]=0;
 x.erase(x[1])
}

But my compiler doesnt like this at all.

Code:

Warning W8012 C:\PlatformClass.h 141: Comparing signed and unsigned values in function Platform::Fall()
Error E2285 C:\MOPEngine.h 168: Could not find a match for 'vector<Platform,allocator<Platform> >::erase(Platform)' in function PlatBreaker()
*** 1 errors in Compile ***

C:\Borland\BCC55\Bin>

I did a google search for this, and something about iterators or something poped up, but how do I return an iterator thats not the absolute beggining or absolute end of a vector? In this example it could work, but in my real code rend and rbegin wont work.

So, how do I make this happy by giving it an iterator (that is what it wants right?)

++iter

Code:

#include <iostream>
#include <vector>

void ShowContentsViaIterator(std::vector<int>& v)
{
std::vector<int>::iterator iter;

for (iter=v.begin();iter!=v.end();++iter)
  {
  std::cout<<*iter<<std::endl;
  }
}

int main() {
 std::vector <int> x;

 x.push_back(1);
 x.push_back(2);

 x[1]=0;
 
 std::cout<<"Before erase:"<<std::endl;
 ShowContentsViaIterator(x);
 
 x.erase(x.begin()+1);
 
 std::cout<<"\nAfter erase:"<<std::endl;
 ShowContentsViaIterator(x);
}

Lol, 7stud, that was probably the mosty helpful 1-word statement ever :P. Thank you guys very much!
