编译状态后的目标代码到底是什么？
What exactly is an Object code after a compiled state?
我知道目标代码是编译阶段之后出现在目标文件中的代码（例如：aaa.obj）。这个文件是什么？包含机器指令？如果是这样，为什么我在该文件中看不到任何 0 和 1。
请帮帮我。
What's an object file in C?
An object file is the real output from the compilation phase. It's
mostly machine code, but has info that allows a linker to see what
symbols are in it as well as symbols it requires in order to work.
(For reference, "symbols" are basically names of global objects,
functions, etc.)
A linker takes all these object files and combines them to form one
executable (assuming that it can, ie: that there aren't any duplicate
or undefined symbols). A lot of compilers will do this for you (read:
they run the linker on their own) if you don't tell them to "just
compile" using command-line options. (-c is a common "just compile;
don't link" option.)
If so why can't I see any 0's and 1's in that file.
您混淆了目标文件的概念和可执行文件的概念。问题是目标文件包含链接器的编译代码和指令（从一个或多个目标文件构建一个可执行文件的程序）。链接器程序的输出实际上是可执行文件，其中包含您期望的零和一。
