interpreted language

This article is reproduced from Wang Gen blog, source address: HTTP://WWW.YINWANG.ORG/BLOG-CN/2017/07/06/MASTER-PL, although Wang Gen is a controversial person, this article some places also write some arrogant, However, this article is very good, I am the same view of programming, language is only second, learning to solve the problem of the thinking and language characteristics is the most important.Right

Special string macros [Cpp] # Define A (x) T _ # x # Define B (x) # @ x # Define C (x) # x Assume that x = 1, the macro definition above will be interpreted as follows: A (1) ------> T_1 B (1) ------> '1' C (1) ------> "1" These functions are mainly used in string processing functions and par

The high-level computer programming language can be divided into compiled and interpreted languages according to the way its programs are executed.A compiled language is a machine instruction that uses a specialized compiler to translate source code into computer recognition for a particular operating system at once. For example, C, C + +, etc. are compiled langu

I caught up with the College Entrance Examination in the past two days. I attended the College Entrance Examination in my house, so I didn't come to the garden for a stroll. Today, my college entrance examination is finished and I am idle. The last time I wrote some text about the printf () function, I felt that I was not very familiar with the input and output, and I was not very complete. There were a few bugs, so I want to continue with the last topic. So what are you doing this time? Let

If all the elements in an array hold a pointer, then we call it an array of pointers. The array of pointers is defined in the general form: DataType *arrayname[length]; [] has a higher precedence than *, which should be understood as: DataType * (Arrayname[length]); The parentheses indicate that the arrayname is an array that contains the length elements, and the outer brackets indicate that each element is of type datatype *. In addition to the different data types for each element, the po

Type: You can use an enumeration type when there are only a limited number of possible values for a variable.05 pointer type: pointer type is a special type of data, stored values are interpreted as an address in memory#include intMain () {intI=0, j=0, x=Ten, y=Ten, z=Ten, t=Ten, B; floatf,f1,f2,f3; /*single-Mesh operation*/x= -x; Y= ++i; Y= j + +; printf ("x=%d,y=%d,z=%d\n", x, Y, z); printf ("i=%d,j=%d\n", i,j); /*Binocular Operation*/I= t%3; J= t/

and software distribution. The Java language is portable. This portability comes from architecture neutrality, and Java also strictly specifies the length of each basic data type. Java system itself is also very strong portability, Java compiler is implemented in Java, Java operating environment is implemented with ANSI C. The Java language is an interpreted

Swift is a new programming language for the development of IOS and OS X applications, however, its development experience has much in common with C or objective-c. Swift provides all the underlying types in C and objective-c, including int representing integers, Double and float for floating-point numbers, bool for Boolean values, and String that represents plain text data. Swift also provides strong support for the two basic collection type Array an

An array is a set of data that has the same type, and each data is called an array element (element). All the elements in the array are contiguous in memory, and the entire array occupies a single piece of memory. with int arr[] = {99, 15, 100, 888, 252}; For example, the array is distributed in memory as shown in the following illustration: When you define an array, you give a list of array names and arrays of lengths, which can be considered a pointer to the NO. 0 element of the array. in t

binary. In decimal format, we use 0 ~ 9 These 10 numbers are used to express all numbers. If they are converted to binary, they can only express all numbers with "0" and "1, in elementary school, the teacher taught us "every ten to one", so we know 9 + 1 = 10; then, in the binary world, 1 + 1 = 10. In binary, "10" (read as zero) is 2 in decimal. In this way, we can use 0 and 1 to express all numbers. But in fact, all data in the computer is expressed by 0 and 1. However, according to the strict

is destined to be slower than the compilation of a large section, like hundreds of times times the speed gap is not surprising. compiled and interpreted, each with pros and cons. The former because of the fast program execution, the same conditions on the system requirements are low, so like the development of operating systems, large applications, database systems, such as the use of it, such as C + +, Pascal/object Pascal (Delphi), VB and other

This is a creation in Article, where the information may have evolved or changed. Do we really need another C-style programming language in this world? It was clear that Google had thought so long ago that in 2009 it borrowed the song of the Ramones Band "hey! Ho! Let's go, officially launched the Go language. Now that the Go language development team has develop

Study notes: history and characteristics of C Steps to write a program Some knowledge of compilers and linker Standard of C The origin of 1.1 C language in 1972, Dennis Ritchie (Dennis Ritch) and Ken Thomson (Ken Thompson) at Bell Labs in the United States invented the C language when developing the UNIX operating system. However, in the design of C

In C language, a typedef is generally used to define aliases (parameter names) for callback functions. Aliases are implemented through macro-defined TypeDef, not as simple macro substitutions. Can be used as multiple objects that declare a pointer type at the same time. Like what: Copy Code code as follows: Char *pa,pb;//pa is a char pointer, but PB is a char character. We can do that. typedef char* PCHAR; Pchar Pa,pb;//pa and Pb a
