C++ in QB? - CletusSnow - 05-26-2024
I think I read somewhere that it is possible to use C++ code within a QB program. But unfortunately I can't find any information about it.
Is it possible, and if so, how?

Thank you for your reply, but I think that is not what I mean.
I was thinking of a possibility similar to using JavaScript within HTML, and without using Libraries.

It's pretty easy:
1. Place your C/C++ functions in a *.h file
2. On the QB64 side bind your functions using a DECLARE LIBRARY block by referencing the *.h file (important: name the file without .h extension)
3. Use the functions on the QB64 as per the declarations.
If you get compiler errors, try to fix it on the C/C++ side, most issues arise with incorrect/unknown typing or namespaces. So try to limit yourself to <stdint.h> types and add namespace prefixes to functions when required (eg. std :: somefunction).
For an easy example see my RegEx implementation.
More stuff to examine in my Libraries collection, especially the Base64, Md5, Des56, Sha2 and standard library stuff.

Ok, thanks a lot. I See. And I need more Coffee. Sometimes I feel like a pirat with two eye patches...

Is it possible, and if so, how?
The Basic file (Both files in the same ordner):
Code: (Select All)
Option _Explicit
'In QB64 mit "Declare Library" wie angegeben
Declare Library "D:\Lab\QuickBasic64\Extern-nicht-Basic\Basic-ruft-C\bfibonacci"
Function fibo& (ByVal N As Integer)
End Declare
Dim As Integer N, rueckgabe
Dim As Single zeitstart, zeitende
Timer On
Cls
Locate 3, 3
Input "Berechnet die Fibonacci-Zahl von: ", N
zeitstart = Timer
Locate 5, 3
rueckgabe = fibo&(N%)
If rueckgabe = -1 Then
Print "Eingabe zu gross!"
Sleep: System
Else
Print Using "Die Fibonacci-Zahl von ## = ###,########"; N; fibo&(N%)
End If
zeitende = Timer
Locate 7, 3
Print Using "Sekunden: ##.#### "; zeitende - zeitstart
End
The C-file ( bfibonacci.h):
Code: (Select All)
#include <stdio.h>
#include <stdlib.h>
long fibo(int n)
{
long x, y;
int i;
//Um bei 3 eine Anzeige von: 1 2 3 zu erreichen
x = y = i = 1;
if (n == 0 || n == 1)
{
return(n);
}
if (n > 40)
{
return(-1);
//sonst Überlauf
}
else while (i < n)
{
x = x + y; y = x - y; i++;
}
return(x);
}

LOL! Speaking of coffee, your humor made me nearly spit mine out all over my keyboard.
Thanks for that, and good luck!
