Example code : Various enum type sizes type {$Z1} TCars1 = (Rover, Jaguar, Honda);// Will fit into 1 byte TFruit1 = (Banana=255, Apple, Pear);// Will exceed one byte {$Z4} TCars2 = (Ford, Nissan, Vauxhall);// Now uses 4 bytes ...
delphi遍历循环 在Delphi 2009 中, for in 循环都能用在什么地方?一、遍历TStrings var List: TStrings;s: string;begin List := TStringList.Create;List.CommaText := 'aaa,bbb,ccc';for s in List do ShowMessage(s);List.Free;end;二、遍历数组 var Arr: array[0..2] of Byte;i: Integer;b: ...
多维数组: var MyArr: array[0..2, 0..2] of Integer; begin //使用 MyArr[1,2] := 100; end; //6. 根据子界定义数组: type TRange = 0..10; var MyArr: array[TRange] of Integer; 使用类型定义: //7. 根据枚举定义数组: type TEnums = (Enum1,Enum2,Enum3); var MyArr: array[...

将C Enum转换为Delphi,可以通过以下步骤实现: 1. 在Delphi中创建一个新的枚举类型,与C中的枚举类型相对应。例如,如果C中的枚举类型为: ```c enum Color { ...
