delphi array
To declare an array in Delphi, you can use the following syntax:
var
myArray: array[indexType] of dataType;
Replace myArray
with the desired name of your array. indexType
represents the data type of the array's index, and dataType
represents the data type of the elements in the array.
To access individual elements in the array, you can use the following syntax:
myArray[index] := value; // Assign a value to an element
value := myArray[index]; // Retrieve the value of an element
Replace index
with the desired index of the element you want to access or modify. Note that array indices in Delphi start from 0.
You can also use loops to iterate over the elements of an array. For example, a for
loop can be used as follows:
for i := 0 to high(myArray) do
begin
// Access or modify myArray[i] here
end;
In this loop, i
represents the current index being iterated over. high(myArray)
returns the highest index in the array.
To dynamically resize an array in Delphi, you can use the SetLength
procedure. For example:
SetLength(myArray, newSize);
Replace newSize
with the desired size of the array.
Remember to include the System
unit in your Delphi code if it's not already included. This unit provides the necessary types and procedures for working with arrays in Delphi.
