本文介绍了如何初始化静态数组?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
TYPE
RDisk =打包记录
R2:数组字节的[1..1024]
etc
etc
end;
如何使用常量声明将R2初始化为零:
CONST
磁盘:RDisk =
(
R:??
);
解决方案
省略字段你想要零:
键入
RDisk =打包记录
R2:array [1..512 ]的字节
I:整数;
D:双
R3:Array [1..512] of Byte;
结束
const
磁盘:RDisk =
(
I:3;
D:2.5;
);
或
code> const
磁盘:RDisk =
(
);
我不知道为什么它工作,它不太适合<一个href =http://docwiki.embarcadero.com/RADStudio/en/Declared_Constants#Record_Constants =nofollow>记录常数文档。
Let's say I have this declaration:
TYPE
RDisk= packed record
R2: array[1..1024] of Byte;
etc
etc
end;
How do I initialize R2 to zero using a constant declaration like this:
CONST
Disk: RDisk=
(
R: ??
);
This is related to Record in record (Cannot initialize)
解决方案
Omit the fields you want to zero:
type
RDisk= packed record
R2: array[1..512] of Byte;
I: Integer;
D: Double;
R3: array[1..512] of Byte;
end;
const
Disk: RDisk=
(
I: 3;
D: 2.5;
);
or,
const
Disk: RDisk=
(
);
I don't know why it works, it doesn't quite fit in Record Constants' documentation.
