What is the source code?

The source code is a machine language that human beings can understand. After writing the code, the programmer will compile the source code into machine code, which may be an executable program exe or something. This is an executable program that we usually use. If you want to add functions or improve programs, you need source code, because people can't write advanced programs through 0 and 1

For example, if you write a document in Word and generate a PDF file, generally speaking, PDF cannot be modified. You can send this PDF to others, but it is not easy for others to modify it. And you have this PDF document (Word document), you can easily modify it and then generate a PDF document. Word document here is equivalent to source code, and PDF document is equivalent to software.

brief introduction

There is nothing to say about code. Broadly speaking, as long as it is written in a programming language, C writes code, and after compilation, it becomes an assembly language program, which can also be said to be code; Then assemble it into a machine language program, which can also be said to be code; However, the calculation of code is also a program, which is generally generalized.

The question of "source code", you wrote it in C, let me see, that's the source code; If you compile the code into. . Exe file and let me run it directly. It is not the source code or the java game you made. If you give me the java code you wrote, it is the source code. Give me the processed executable file, not the source code.
