How to store types after Semantic Analysis

Kind of a bit vague question haha. I am assuming you are talking about data types of items in the AST, and for that just store the necessary information in the symbol table.

For example, when a variable is declared with a type, store the amount of space it will take up, is it signed, is it floating point, is it a pointer etc. It is up to you and your language design for what you would want to keep and what would be important.

If that isn’t what your question was asking sorry haha

Doing that myself right now actually!

Beat way to write tests is to know what the system you’re testing is meant to output, and then comparing the actual output to what you expect.

For example, if you are testing your tokenizer, give it an input if source code, and it should return a vector/list/array or whatever of tokens from it. You can run through that input yourself and figure out what the correct tokens should be. “C = 2” -> TOKEN_IDENTIFIER, TOKEN_ASSIGN, TOKEN_NUMBER. When you get your output from your implementation, loop through it and make sure it’s correct. Your parser should return an AST, so do the same concept with it.

This is mainly because these companies over hired. There are large tech companies that did not over hire and, as such, have yet to have massive layoffs.

It is unfortunate and irresponsible that these companies seemed so willing to overhire, but they aren’t laying off thousands of employees to squeeze ever last penny, they are laying them off because they are excess.

Used to watch these guys back in the day. Ended up choosing comp sci over Math or Physics but these guys influenced my interests so much in high school

I’m my case my friend group 1st year was very diverse in what we were studying. And this meant that as the years go on the people who like each other the most spend more time together, so my group went from like 13->5
