Thread: Selection Sort problem #2

Hey guys, I've had a similar topic before - but this isn't about the fundamental workings of Selection Sort this time.

I am using vectors in correspondence with the selection sort algorithm. (Just for fun and games)...However, I'm getting an annoying error that I cannot think of why it's happening (Because I changed the code around a bit - but this line is deciding to act up now...When it's fundamentally the same as it was before).

Anyhoo - here's the code.

Code:

#include <iostream>
#include <vector>

using namespace std;

int main()
{//Main
	vector<int> Selected_Numbers;
	int number;
	bool quit = false;
	int decision;

	while(!quit)
	{//While
		cout<<"(1)Enter a number, or (2)quit, or (3)continue"<<endl;
		cin >>decision;

		switch (decision)
		{//Switch
		case 1:

				cout<<"What number is it?"<<endl;
				cin >>number;
				Selected_Numbers.push_back(number);
				break;

		case 2:
			
				quit = true;
				break;

		case 3:
			
			int LowestNumber = 0;
			int CurrentNumber = 0;
			

			for(vector<int>::iterator iter = Selected_Numbers.begin();
				iter != Selected_Numbers.end(); ++iter)
			{//For1

				CurrentNumber = *iter;

				if(LowestNumber <= CurrentNumber)
				{//If1
					 LowestNumber = CurrentNumber;

					 Selected_Numbers.begin() = LowestNumber; 
/*^This is the line generating
the problem. Compiler says 
'error C2679: binary '=' :
no operator found 
which takes a right-hand 
operand of type 'int' 
(or there is no acceptable 
conversion)' */

				}//Close if1
				else
				{//else1
				cout<<"Next Number...."<<endl<<endl;
				}//close else1
			}//close For1
		
			
		cout<<"Alrighty then...All has been arranged from lowest - highest"<<endl<<endl;
			
		for(vector<int>::iterator iter = Selected_Numbers.begin();
			iter != Selected_Numbers.end(); ++iter)
			{//For2
				cout<<*iter<<endl;
			}//close For 2
			break;
		}//Close Switch

	}//Close While
		
	system("pause");
}//Close Main

Any help will be much appreciated....I do understand what the error says - but I don't know why it's saying it! Cos before, it worked exactly the same (I had to make a change to the code to get Selection Sort to work, by adding the variable 'current number').
