Lists STL

[armen_shlang]

small question about LIST stl...
My code looks something like this...

#include <list>
#include <iostream>
using namespace std;


void main()
{
	list<int> randomNums;
	int number20 = 0;
	while( number20 < 5 )
	{
		(number20++);
		randomNums.push_back((2*number20) + 1);
		randomNums.push_back(2*number20);
	}
	list<int>::iterator iter = randomNums.begin();

	randomNums.erase(randomNums.end());

	for( list<int>::iterator iter = randomNums.begin() ; iter != randomNums.end() ; iter++)
	{
		cout << (*iter) << endl;
	}

}

And i get en error when trying to use the erase command with the randomNums.end(); which makes sense.
>>>HOW CAN I ERASE THE LAST ELEMENT FROM THE LIST?

also when I try to erase using this code:
[code]
randomNums.erase(iter++);
[/coode]
it won't erase the second entry.
>>WHY DOES LIST FUNCTION LIKE THIS??
