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

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,

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

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

should be:

[code]
#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]

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? 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

[Zaei]

MS of course =).
