Jun 1, 2020 · Lower-level CMSC courses provide extensive debugging and development help in office hours, but upper-level CMSC courses expect students to complete projects with minimal extra help. Therefore in CMSC 330, we will provide less debugging help than some students may be used to. Introduction. Over the course of Projects 4a and 4b, you will implement MicroCaml — a dynamically-typed version of OCaml with a subset of its features. Because MicroCaml is dynamically typed, it is not type checked at compile time; like Ruby, type checking will take place when the program runs.CMSC 330 Spring 2021 5 Heap memory – allocated when needed (by malloc), and freed (by free) when no longer needed Static memory – (global variable g) at a fixed address, never freed LIFO/stack memory – (parameter y, local variables p, z) allocated at start of function call, freed when function returns CMSC 330 \n.
