What is translated > Special assignments

 

In Delphi the contents of array variables of the same type can be assigned directly. In C++ the assignment has to be done via pointers to the first array element by means of the functions "strcpy" or "memcpy":

 

Assignments to character arrays is done with "strcpy".

 

var

 chr10 : array[1..10] of char;

begin

 chr10 := 'abcdefghij'; 

 

->

 

char chr10[ 10/*# range 1..10*/ ];

strcpy( chr10, "abcdefghij" );

 

 

Assignments of other static arrays are done with "memcpy".

 

 

procedure test(xArr: TObjectArray);

var

  arr: TObjectArray;

begin

  arr := xArr;

end;

 

->

 

void __fastcall test( const TObjectArray& xArr )

{

  TObjectArray arr;

  memcpy( arr, xArr, sizeof( TObjectArray ) );

}
