嗨!大家好,我们又见面了,这一期首先来为大家讲一讲数组和模块。关于数组,它可以用相同的名字来引用一系列变量(变量即可以改变的量,如:x、y,而常量就是不可改变的量,当他被创建时就被赋予了不可改变的值,如:e、π。),并用数字,即索引来识别它们。一个数组,除非它的类型为Variant之外,它当中所有的元素都具有相同的数据类型。每个数组都有上下界,在上下界当中的元素是连续的。下界不得超过-231即-2,
Hello, everyone, we met again. This time, we will first talk about arrays and modules for everyone. Regarding arrays, it can refer to a series of variables with the same name (variables are variables that can be changed, such as: x, y, and the constants are immutable quantities, which are assigned immutable values when they are created, Such as: e, π.), And use numbers, that is, the index to identify them. An array, unless its type is Variant, all elements of it have the same data type. Each array has upper and lower bounds, and the elements in the upper and lower bounds are continuous. The lower bound cannot exceed -231 or -2,
