我想删除之后的空白\n.
例如,username 123\n ugas 423\n peter 23\n asd234会成为username 123\nugas 423\npeter 23\nasd234.
这是函数组合运算符的定义?
(.) :: (b -> c) -> (a -> b) -> a -> c
f . g = \x -> f (g x)
Run Code Online (Sandbox Code Playgroud)这表明它需要两个函数并返回一个函数,但我记得有人用英语表达了逻辑
男孩是人 - >阿里是男孩 - >阿里是人
请帮忙.
谢谢.
我用或运算符定义了一个规则,但它返回多个true或false.
isloanaccept(Name,Guarantor,LoanType,LoanAmount,LoanTenure)
:- customer(Name,bank(_),customertype(_),
citizen(Ci),age(Age),credit(C),
income(I),property(_),bankemployee(_)),
Ci == 'malaysian',
Age >= 18,
C > 500,
I > (LoanAmount / LoanTenure) / 12,
isguarantor(Guarantor,Name),
ispersonalloan(LoanType,LoanAmount,LoanTenure);
ishouseloan(LoanType,LoanAmount,LoanTenure);
isbusinessloan(LoanType,LoanAmount,LoanTenure);
iscarloan(LoanType,LoanAmount,LoanTenure).

实际上,我需要检查贷款类型是否符合特定贷款要求并与一般规则相结合.
换句话说,我需要像这样定义上面的规则.
Ci == 'malaysian', Age >= 18,C > 500,
I > (LoanAmount / LoanTenure) / 12,
isguarantor(Guarantor,Name)
Or with (ispersonalloan(LoanType,LoanAmount,LoanTenure);
ishouseloan(LoanType,LoanAmount,LoanTenure);
isbusinessloan(LoanType,LoanAmount,LoanTenure);
iscarloan(LoanType,LoanAmount,LoanTenur)

它应该在命令行中返回1个true/false而不是多个语句.
每个或者规则返回1布尔值,这是我想要的后检查命令行中的规则.我需要这样(一般规则和(多重或规则)).
如何组合几个或返回1布尔值的规则?
请帮忙.
谢谢.

我想自动化一些应用程序。此应用程序由 Web、移动(Android + IOS)和 API 组成。如何针对这种情况组织这个项目。我使用 Java 在 selenium 中实现自动化。在 C# 中,一次可以创建一个由多个子项目组成的项目。如何在Java中做到这一点?
请指教。

我想知道IO()函数可以返回元组,因为我想将这些函数作为另一个函数的输入.
investinput :: IO()->([Char], Int)
investinput = do

username <- getLine
putStrLn "Enter Invest Amount : "
tempamount <- getLine
let amount = show tempamount
