Should I learn C89 or C99?
8 Answers. There is no reason to learn C89 or C90 over C99- it’s been very literally superseded. It’s easy to find C99 compilers and there’s no reason whatsoever to learn an earlier standard.
What is the difference between CS50 and CS50 AP?
Hello, world! CS50 AP is an amalgam of two courses, CS50’s Introduction to Computer Science, otherwise known as CS50x, and CS50’s Understanding Technology, otherwise known as CS50T. CS50 AP is only for students in high school. Students not in high school should take CS50T and CS50x instead.
Is C89 still used?
This usage is strictly incorrect, but too firmly entrenched to ignore. The 1990 ISO C standard describes the same language, and was officially adopted by ANSI, making the 1989 standard obsolete. If you want to refer to the language defined by the 1989 ANSI C standard (and described in K&R2), call it “C89” or “C90”.

Is Harvard CS50 certificate worth it Reddit?
If you are just wanting to learn then a certificate may not be necessary, if you’re wanting to add it to a resume or something, then yes, it’s worthwhile. It’s not a replacement for a CompSci degree, but if you don’t have one this certainly helps. You can opt to pay for the certificate at any time.
