Essentially, this is when the compiler takes the assembly code and assembles it into machine code in a binary format. After researching this online, I figured out that a lot of compilers will allow you to stop compilation at this step. This would be useful for compiling each source code file separately. This saves time later if a single file changes, since the developer -will only need to re-compile single file. +will only need to re-compile a single file. *** Step 4 |
