C++ is only slighter faster than VB

[made_of_asp]

Hello,

I used GetTickCount API and i found out that my two equal programs written on C++ and VB, had VB version was only 196 points slower than C++ and VB had window intilized while C++ was running in Console.

Is this realy true? I heard that C++ was much faster and efficient than VB :B :) :D

C Version (took 6783 points):


#include "stdafx.h"
#include <iostream.h>
#include <windows.h>

int main(int argc, char* argv[])
{
int x;
int ticks;

x = 5 * 8;
ticks = GetTickCount() / 1000;
cout << ticks;
cin >> x;
return 0;
}


VB Version:


Dim x As Integer
Dim ticks As Integer

x = 5 * 8
ticks = GetTickCount / 1000
Me.Caption = ticks


made_of_asp,
:rolleyes:

Well, technically C++ is much faster than VB, but your example really doesnt prove it well. On small programs/functions, like the one you specified, the speed difference is relatively insignificant. But on much larger programs, VB can get to be a little bogged down and will run algorithms and long processes much slower because of various crap.

Here is a language comparisonC++ vs. Visual Basic (http://www.dummies.com/Technology/Programming/Programming_Fundamentals/0-7645-0835-0_0009.html)

Plus, none of his code is shwoing how long it took to execute

should be:


#include "stdafx.h"
#include <iostream.h>
#include <windows.h>

int main(int argc, char* argv[])
{
int x;
int ticks;
ticks=GetTickCount();
x = 5 * 8;
ticks -= GetTickCount();
cout << ticks;
cin >> x;
return 0;
}

[code]

[code]
Dim x As Integer
Dim ticks As Integer
Ticks = GetTickCount
x = 5 * 8
ticks = ticks -GetTickCount
Me.Caption = ticks

While we are at it: On average C++ is an order of magnitude (10 times faster ) than VB code.

why? VB executes inside a virtual machine, just like java does in IE. It does not run as native image code.

10 times faster? You are kidding!

C++ is sooo hard :(

VB does not run inside a virtual machine when it is compiled to Native Code.

That's one of the best solutions if the VB runtime dependencies aren't a problem.

It means you don't have to learn much of the API which takes quite a while to learn well.

Also, VB is all COM, which adds overhead as well.

WinAPI: bad paradigm
COM: performance hit
VB: very bad paradigm polluted slowmoving fat bastard

What are you going to do when you have to accomodate languages that arent OOP?

Me or microsoft? :D microsoft is the one accomodating for function based languages, I'm for new innovations :)

[parksie]

I'm doing the wrappers between the API and whatever you're using...in this case it's a functional->OOP layer.

I don't understand what Ked's doing at the moment :p

[Zaei]

MS of course =).
