VBA数组(六)动态数组 大家好,前面已经介绍过了如何声明数组、数组赋值、静态数组和数组函数等等知识点,本节主要讲解动态数组。 动态数组的定义 如果在声明数组不确定数组的大小,先不固定数组的大小,而在程序在运行时使用Redim语句重新定义数组大小即为动态数组。(而如果声明数组时即确定数组大小即为静态数组。) 声明动...

1、整型数据的分类整型数据的一般分类如下:(以下说明的在内存中所占的字节数均是在vs2012这个开发工具里面的)基本型:类型说明符为int,在内存中占4个字节。短整型:类型说明符为short int或short。所占字节和取值范围均与基本型相同。长整型:类型说明符为long int或long,在内存中占4个字节。长长整型:类型说明符为...
