, and console programs can be written. If you want to use c for more development, you need to use Windows to learn WIN32 APIs, or use a variety of third-party interface libraries for GUI, and use Sockets for network programming, I also need to learn a lot of operating system principles, computer networks, algorithms, and so on !!! Even string processing is not easy! However, if you want to directly operate the memory, you are afraid of the trouble of the assembly language. Use C! C ++ is too com

Application Scenario: the backend of a statistical queryProgramThe corresponding processing functions are called Based on the query name string. In general, you can use a Global Registry to match the name string with the function name. However, LISP programmers are very lazy. Since the lisp environment itself already provides a name registration mechanism, why do we need to write one? In fact, the core

Talk about my own background, I am a dabbler programmer, do anything like to know more and try again, I have been exposed to many languages, most of them as tools to useMost of my work now lies in data mining and machine learning, and web development, and the first language I've worked with is Python, where I learned about the concept of functional programming.Speaking of Lisp is said to be a copy of Lisp P

For example, use Lispbox under Windows platform to start emacs+slime through

To learn Lisp, you can see SICP, I spent a summer time to chew SICP, chew to chew not move, but found that really learned a lot of interesting things, and then go to play Haskell, probably learn Haskell intermittent also have half a year of time, But I feel that what I learned in Haskell is much more than what I've learnt in SICP, probably because I'm not strong enough to understand the essence of SICP.Learning Haskell has taught me how wonderful it i

 The function required by the topic requires the following three things to be done: Write a function that accepts three numbers as a parameter Determine the larger of the three numbers in two Calculates the sum of squares of a larger two numbers (the sum of the squares of two numbers) We're going to do these three tasks from the back to the next step.CSDN No Lisp.

LAMDBA is actually an anonymous function.The lambda syntax for defining Lisp is very simple, as follows:(Lambda ([parameter]) [Experssion])There are three ways to invoke the lambda syntax, as follows:First type: ((lambda (x) (+ x 1)) 100); Add parameters directly to the backThe second type: (Apply # ' (Lambda (x) (+ x 1)) ' (100)); Use the Apply function to pass in a list table in the last argumentThe third type: (Funcall # ' (Lambda (x) (+ x 1) 100))
