How compilers work
Conclusion
This article offered a brief look at how compilers parse and prepare source code. Keep in mind that not all compilers adhere to the approach described in this article. For example, one-pass compilers do without an internal representation of the code and generate the object code in a single pass. Also, the steps presented in this article sometimes do not occur in distinct phases but are, instead, interwoven.
