Dup [ ( <value> ) ] ;
Description
The dup(value); return a space data filled with the given value. For example a 10 dup(0) return an array of 10 elements, all with a zero value.
Example 1
import "mod_say";
global
array[] = 10 dup(0);
begin
say ( sizeof(array)/sizeof(array[0]) );
end
This example prints 10 because the size of array is ten and the size of the first element is one.
Example 2
import "mod_say";
global
int array[5] = 1 , 4 dup(0);
int arrayPosition;
begin
for ( arrayPosition = 0 ; arrayPosition < 5 ; arrayPosition = arrayPosition + 1 )
say ( array[arrayPosition] );
end
end
This example prints:
1 0 0 0 0
As it duplicates "0" four times in the array data.
