Is it possible to make a user-defined array function? Thank you so much!

Excuse me,

I was wondering whether anyone superior here could enlighten me.

Is it possible to make a user-defined array function?

If it could be done, we must be able to transfer the array name as a parameter to the function.

Could someone give me an example?

Thank you so much!

You pass the array name by reference . . . for example . . .

double Array[];
double AnotherArray[];

ResizeArray(Array, 30);
ResizeArray(AnotherArray, 200);


void ResizeArray(double& ArrayToBeResized[], int NumberOfElements)
   {      

   ArrayResize(ArrayToBeResized, NumberOfElements);

   }

Thank you so much, RaptorUK!!!

By the way, could you please show me another example on how to make a multi-dimension array function?

Thank you very much!

1. You can only modify the first index of the array

   #define SIZE 10
   static double   vHist[][SIZE];          ArrayResize(vHist, nHist);
   // array is now [nHist][SIZE]
   

2. If you want both indices to be dynamic, you have to do it yourself

   int dim2; double arr[];
   void   setDim(int d1, int d2){ dim2=d2; arrayResize(arr, d1*d2); }
   void   setArr(int d1, int d2, double v){ arr[d1*dim2+d2] = v;    }
   double getArr(int d1, int d2){ return( arr[d1*dim2+d2] );        }
   :
   setDim(2,3); // looks like array[2][3]
   setArr(1,2,v) // looks like array[1][2]=v

Your code is great!
