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 such as exe. This is an executable program that we usually use. If we want to add functions or improve programs, we need source code, because people can't compile advanced programs through 0 and 1

For example, if you write a document in Word and generate a PDF file, generally speaking, the PDF cannot be modified. You can send this PDF to others for reading, but it is not easy for others to modify it. You have this PDF manuscript (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, it is also the program that calculates the code, which is generalized.

The question of "source", 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.
