how to set up an array in delphi
To set up an array in Delphi, follow these steps:
1. Declare the array: Use the "var" keyword to declare the array along with its size and data type. For example, to declare an array of integers with a size of 5:
```delphi
var
myArray: array[0..4] of Integer;
```
2. Initialize the array: You can initialize the array with values at the same time as you declare it, like this:
```delphi
var
myArray: array[0..4] of Integer = (1, 2, 3, 4, 5);
```
3. Access elements of the array: You can access elements of the array by using the index value, which starts from 0. For example:
```delphi
writeln(myArray[2]); // This will output the value at index 2, which is 3 in this case.
```
4. Loop through the array: You can iterate through the array using a for loop. For example, to print all elements of the array:
```delphi
var
i: Integer;
begin
for i := 0 to Length(myArray) - 1 do
begin
writeln(myArray[i]);
end;
end;
```
These are the basic steps to set up an array in Delphi. You can also use dynamic arrays if you need to change the size of the array during runtime.
