  • What are the characteristics of a typeless programming language . . .
    BCPL was typeless in that it had a machine word of a predetermined size as its only data type, and that word could be used as an integer, pointer, character etc at will It made writing compilers easier, and using them harder! Parts of this philosophy made their way into its successor B, and thence into the C language that finally succeeded it
  • Grammar types constraint after adding a couple of types (and a . . .
    Grammar types constraint after adding a couple of types (and a statement involving them) to a "typeless" language Ask Question Asked 8 years, 4 months ago Modified 8 years, 4 months ago
  • Implicitly typed vs untyped? - Computer Science Stack Exchange
    What are the differences between an implicitly typed programming language and a untyped programming language? Let me explain the above question and what I have thought about it My question co
  • What is a type definition? - Computer Science Stack Exchange
    The extreme example is assembly, which is technically typeless - the concept of types simply doesn't exist Another example is liberal type conversions, including those that may lose some information A rather interesting example is pointer arithmetic in a language like C, which makes it easy to get around the type system
  • Are assembly languages untyped? - Computer Science Stack Exchange
    There are a number of strongly-typed intermediate languages for various runtime environments, which often have similarities to assembly languages while enforcing high-level type safety guarantees Examples include JVM class file bytecode and NET CIL
  • How does the Stockham FFT work? - Computer Science Stack Exchange
    Both algorithms are DIT, but the main difference is in memory access patern Cooley-Tukey - the most popular form of transformation from DFT to FFT comes from cache awareness, which is optimal for CPU pipeline Cooley-Tukey in first phase reverses bit order while Stockham changes order at each stage This is observable if you take look at edges - once you have half of the data it stays in
  • What is the difference between a scripting language and a normal . . .
    Ousterhout characterized scripting languages as "typeless" (including what many call dynamic typing), and as emphasizing rapid development; they are usually implemented by interpreters Now, one must be careful not to assume that a single author's conceptual model is authoritative
  • What would dynamically-typed languages actually do if type enforcement . . .
    There are probably more statements that the 3 languages are dynamically typed but there is also considerable amount of statements about their untyped ness or typeless ness
  • What is a Key in computer science? - Computer Science Stack Exchange
    A key in the context of data structures (such as in the book CLRS) is a value (often an integer) that is used to identify a certain component of a data-structure Often, keys determine how the underlying data is stored or manipulated For example, in binary search trees we have that for every node, the key of that node is larger than the keys in the left sub-tree and smaller than those in the
  • Why does a lock ordering prevent deadlocks?
    The four necessity conditions for deadlock are: Mutual exclusion Hold and Wait No preemption Circular Wait Let there be two processes threads - P1 and P2 and two resources - R1 and R2 Now assume that both resouces must be acquired to perform a certain task T Assume that requirements 1 to 3 are guaranteed If you allow the processes to run concurrently to perform T such that P1 tries to
