interpreted language

"Strongly typed language/weakly typed language" Strongly typed languages tend to be intolerant of implicit type conversions. Strongly typed languages are Java, C #, Python, and so on. The example is as follows (Python): >>> 875>>> + 8 ' Traceback (most recent): File " Weakly-typed languages tend to tolerate implicit type conversions. Weakly typed languages include C, C + +, JavaScript

I. Compiled and interpreted typeWe first look at the compiler type, in fact, it is the same as the assembly language: There is a translation program to convert our source code, generate the corresponding executable code. This process is a bit more professional, called compilation (Compile), and the compiler responsible for compiling is naturally called the compiler (Compiler). If we write the program code i

Recently, the major Internet companies online written tests, programming topics in the compiler only support C + +, Java, and even some support javascrpit and Pascal, is not support Python. Let me always used to be accustomed to the python I spit blood, so today, or familiar with Java, lest continue to be abused. In the course of learning, you see such a controversy as "Java, Python who is a compiled language, who is an explanatory

Running a compiled language is relative to the existence of an interpreted language, the compiled language first compiles the source code to generate machine language, and then the machine runs the Machine code (binary). It is a compiled

The difference between the Interpretation Language and the compilation language lies inProgramDuring each running, the program must be dynamically interpreted and executed through the interpreter. The program written in the interpreter language is sometimes called a script. Generally, the reader can directly read the p

1.compile: Advantages: Compiled languages need to be compiled once, run directly, do not need to translate, so the compiler language program execution efficiency is high. Poor portability and can only run on compatible operating systems 2.interpret Advantage: The explanatory language is translated when the program is run, and every statement is executed. Such explanatory

information, see PythonImplementations on the Python wiki. I'm glad to tell you that python is not simply an explanatory language. The python interpreter we usually call is actually Cpython. During execution, python will. the py file is compiled into an intermediate bytecode and stored in the memory. Then, the bytecode is interpreted as a machine-identifiable binary code during actual execution. By default

Compiled languagesMany of the traditional programming languages, such as Fortran, Ada, Pascal, C, C + +, and Java, are compiled languages. These languages require that the source code that we have written be converted into a target tag (object codes), and this process is called "compiling".When you run the program, read the object code directly. Because the compiled object code is very close to the bottom of the computer, the execution is very efficient, which is the advantage of a compiled lan

(machine language) before the source program executes, so its target program can be executed independently from its language environment, which is more convenient and efficient to use. However, once the application needs to be modified, the source code must be modified before the new target file (*) is recompiled. OBJ) to execute only the target file without source code, modification is inconvenient. Most

The Java language is extraordinary.1. You can say it is compiled. Because all Java code is compiled,. Java is useless without compilation.2. You can say it is interpreted. Because Java code cannot be directly run after compilation, it is interpreted to run on JVM, so it is interpreted to run, and that is even explained

checksSecurity analysis tools cannot handle some of the behavior of dynamic languagesTherefore, dynamic languages are sometimes considered unsafe. But from the idea of design, such as:One design philosophy of Python is to trust programmers. If there's a problem with the code, it's your problem, not the Python problem. So the code is concise.Java, in contrast, does not trust programmers. Requires a step-by-step writing code that requires a compiler to do a static check. So the code is lengthy.Tw

The interpreted language is not compiled into machine language until the machine executes, and is interpreted as a machine language by the side execution side, such as Java, PHP, Perl, Shell, C #, and of course Java and C # are compiled into intermediate rows first. class by

Static languageWhen you write code, you must specify a specific type of language for the variable. such as Java, C + +Dynamic languageInstead of specifying an explicit type for a variable when writing code, the interpreter determines the type of the variable at run time, based on the usage of the variable. such as Python, JavaScript# python's dynamic characteristics m = ten'hello'print m #print ' Hello 'Strongly typed languagesThe variable must ha

The best way to interpret C's statement is to read it in English. The truth is very simple, because C language was invented by Americans. To simplify the problem, const and volatile are not considered here. Next, follow these steps to explain C's statement. First, focus on the identifier (variable name or function name ). The derived types (pointers, arrays, and functions) are prioritized from the nearest point of the identifier ). The priorities a
