ShoneSharp Language (S #) design and use introduction series (7)-Boolean Bool and Object Author: Shone

Disclaimer: you are welcome to repost the original article, but please indicate the source, https://www.cnblogs.com/shonesharp.

Abstract: Boolean value (corresponding to the bool of C #) indicates the status "yes" or "no", corresponding to the keywords "true" and "false. An object (corresponding to the object in C #) represents any object. It is a base type of all types, and the keyword null indicates an empty object. Objects have a lot of usage in S #. If you are familiar with them, you will understand:Check whether a mountain is a mountain, whether a mountain is a mountain, or whether a mountain is a mountain..

Software: S # language editor, runtime environment. NET 4.0, green software, single EXE run directly, no side effects. Online drive download link for https://pan.baidu.com/s/1dF4e08p

 

Blog writing is still very hard, so please stick to it. After introducing the Boolean and Object types today, we will go to the S # special introduction, let's look at it to see if it can attract more popularity:

Series (7)-the best "formula" Style

Series (8)-first-class citizens "functions" are cool

Series (9)-rich children's "statement" does not show off wealth

Series (10)-"class" dressing and dressing into "table"

1. Boolean

Boolean (corresponding to the bool of C #) indicates yes or no. S # reserves two keywords true and false. Of course, you can also enter True/False, or/No.

Boolean values are generally used for logical judgment. Almost all modern languages support this type.

Ii. Object

An object (corresponding to the object in C #) represents any object and is a base type of all types. S # reserves a keyword null for it, indicating a null object.

Programming Languages have always argued about the advantages and disadvantages of strong and weak types. The root cause is the existence of objects (pointers in C ++. My personal opinions on strong and weak types take the moderate way, and I think it is necessary to support them. They have their own advantages and disadvantages.

ObjectThere is a lot of use in S #. If you are familiar with it, you can reach the realm of Meditation: Watching mountains are mountains, watching water is water; watching mountains are not mountains, watching water is not water; see mountains or mountains, see water or water.

Let alone S # code:

{
     1 + 2,
     1 + [10, 20],
     [1, 2] + 10,
     [10, 20, 30] + [1, 2],
     cos (30),
     cos ([10, 20, 30]),
     cos ({10, [20, 30], 40}),
     cos ({
         a = 10,
         b = 20,
         c = [30, 40],
         d = {50, 60},
         f = {m = 90}
     })
}
//Calculation results:
{
     3,
     [11, 21],
     [11, 12],
     [11, 22, 32],
     0.86602540378443871,
     [
         0.984807753012208,
         0.93969262078590843,
         0.86602540378443871
     ],
     {
         0.984807753012208,
         [
             0.93969262078590843,
             0.86602540378443871
         ],
         0.766044443118978
     },
     {
         0.984807753012208,
         0.93969262078590843,
         [
             0.86602540378443871,
             0.766044443118978
         ],
         {0.64278760968653936, 0.5},
         {0}
     }
}
