    HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...

  4. It is known as the "Wizard Book" in hacker culture. [1] It teaches fundamental principles of computer programming, including recursion, abstraction, modularity, and programming language design and implementation. MIT Press published the first edition in 1984, and the second edition in 1996.

    In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...

    BASIC-E was Eubank's master's thesis project. [1] [2] It was developed in PL/M by Eubanks for Gary Kildall's new CP/M operating system while both men were at the Naval Postgraduate School in Monterey, California. [1] [2] BASIC-E was based on a BASIC compiler originally written by Gary Kildall in 1974. [1] [2]

    This solves the semi-predicate problem, allowing output and errors to be distinguished, and is analogous to a function returning a pair of values – see Semipredicate problem § Multivalued return. The usual destination is the text terminal which started the program to provide the best chance of being seen even if standard output is redirected ...
