Source Code vs Object Code
Posted September 10, 2022 by Rohith ‐ 2 min read
ource Code is an assembly code or a high-level code- that a programmer generates (human-generated code). These types are comparatively very easy to read as well as modify. Object Code is a machine-understandable one. An object code comprises various low-level codes- that a translator or compiler generates from the source code.
Difference Between Source Code and Object Code are stated below
|Generation of Code
|A programmer generates a source code. Thus, it is human-generated.
|A compiler or any other type of translator generates an object code. Thus, it is machine-generated.
|Level of Code
|This code is of a high-level type.
|This code is of a low-level type.
|This type of code exists in plain text. It is because we write it using a high-level type of programming language.
|This type of code exists in binary format. It is because it is a translated form of code that roots from the source code.
|Understandable by Humans
|Any human can understand a source code.
|A machine can understand an object code- not a human.
|Understandable by Machines
|Machines cannot directly understand a source code unless translated.
|Any machine can directly understand as well as execute an object code.
|Languages Used for Writing Code
|We write these types of codes in various high-level languages, such as Python, Java, C, C++, or the assembly language.
|An assembler, a compiler, or any other form of translator writes these codes into the machine language from the source code.
|Ease of Modification
|One can easily modify these codes.
|You cannot modify these codes.
|A source code can have comments by the programmer for an overall better understanding.
|An object code lacks any kind of comments for the machine to understand.
|Number of Statements
|As compared to the object code, the number of statements is comparatively less.
|As compared to the source code, the number of statements is comparatively more.
|Performance of Code
|A source code performs way less than the object code because it is not very close to the machines.
|An object code performs more and better than the source code because it is comparatively very close to the machines.
|Relations with Assemblers, Compilers, Translators
|The source code acts as the input to an assembler, compiler, or any other type of translator.
|The object code acts as the output of an assembler, compiler, or any other type of translator.
|It is not a system-specific type of code.
|It is a system-specific type of code as it easily runs on machines.
|Ease of Changes and Alterations
|You can easily change the source code over the course of time.
|You need to compile the source code or translate it using any other translator after making the necessary changes- so that it reflects in the recent object code (modified one).
