Thread: Linked Lists

Why not use the vector std class? And what´s a RPN calculator?

what´s a RPN calculator?

Reverse Polish Notation. e.g. instead of 8+8, its 8 8 +

Well, it´s an vector class
It´s kind of like a linked list, but easier to use, has more functions and is more failsafe since it´s a standard class coming with all iso compilers.

Here´s an example:

Code:

#include <iostream>
#include <vector>

using namespace std;

void main()
{
	vector<int> myvector;
	int a = 5;

	// Add two numbers to myvector
	myvector.push_back( a );
	myvector.push_back( a+1 );

	// Print all item in myvector
	for (int i=0; i < myvector.size(); i++)
		cout << myvector[i] << endl;

	// Delete the first item in myvector
	myvector.erase( &myvector.at(0) );

	// Delete all items
	myvector.clear();
}
