Generally, applications written in high-level programming languages are called source programs. This kind of program cannot be run directly on the computer and needs to be translated into a machine by a corresponding language processing program. language program before it can be run.

Introduction to relevant knowledge points:
High-level language (high-level programming language) is not It refers specifically to a specific language, but includes many programming languages, such as the popular java, php, c, c, C#, pascal, python, lisp, prolog, FoxPro, Easy Language, Chinese version of C language, etc. , the syntax and command formats of these languages are different.
High-level language has nothing to do with the computer's hardware structure and instruction system. It has stronger expression ability, can easily express data operations and program control structures, can better describe various algorithms, and is easy to Learn to master.
However, the program code generated by high-level language compilation is generally longer than the program code designed in assembly language, and the execution speed is also slower. Therefore, assembly language is suitable for writing programs that require high speed and code length and programs that directly control hardware.
High-level languages, assembly language, and machine language are all languages used to write computer programs.
The above is the detailed content of What is an application written using a high-level programming language called?. For more information, please follow other related articles on the PHP Chinese website!
