This paper will introduce the function systems approach to study the mathematical properties of Backus functional programming language FP [1] . Here, a function system is defined as a set of functions of FP. In the paper, we define the notions of complete, orthogonal and orthonormal systems, ...
Related to Function (programming): Functional programming languagessub·rou·tine (sŭb′ro͞o-tēn′) n. Computers A set of instructions that performs a specific task for a main routine, requiring direction back to the proper place in the main routine on completion of the task. American ...

Scala is both object-oriented and functional. It is a pure object-oriented language when the value is an object and functional language when every function is a value. If you know Java, it’s worth learning Scala. Scala has features of Java such as its Object-Oriented Structure and its ve...
(programming) (FP) A program in a functional language consists of a set of (possiblyrecursive)functiondefinitions and an expression whose value is output as the program's result. Functional languages are one kind ofdeclarative language. They are mostly based on thetyped lambda-calculuswith constant...
a programming language is a set of instructions that tell a computer to perform certain tasks. it's like a spoken or written language, but instead of being used to communicate with people, it's used to control the behavior of machines. just like there are many different human languages, ...

of atof; all parameter checking is turned off. This special meaning of the empty argument list is intended to permit older C programs to compile with new compilers. But it’s a bad idea to use it with new programs. If the function takes arguments, declare them; if it takes no arguments...
So, laziness is the idea that if you call a function in a normal imperative language or call-by value language, then before calling the function you’re going to evaluate the arguments to the values of those arguments and then you’ll pass them to the function. In a lazy ...
2013 《The C++ Programming Language》4th edtion. 历史过程细节略过不表。 每个章节最后,Bjarne都会给一些建议(去做的事情),第一章的建议如下: 尽可能直接表达概念; Represent ideas (concepts) directly in code, for example, as a function, a class, or an enumeration; 让你的代码既高效又优雅; Aim ...
