  2. Goto - Wikipedia

    en.wikipedia.org/wiki/Goto

    "GOTO" key on the 1982 ZX Spectrum home computer, implemented with native BASIC (one-key command entry).. Goto is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.

  3. Unreachable code - Wikipedia

    en.wikipedia.org/wiki/Unreachable_code

    Unreachable code is generally considered undesirable for several reasons: It uses memory unnecessarily; It can cause unnecessary use of the CPU's instruction cache. This can also decrease data locality; Time and effort may be spent testing, maintaining and documenting code which is never used Sometimes an automated test is the only thing using ...

  4. Spaghetti code - Wikipedia

    en.wikipedia.org/wiki/Spaghetti_code

    Spaghetti code is a pejorative phrase for difficult-to-maintain and unstructured computer source code. Code being developed with poor structure can be due to any of several factors, such as volatile project requirements, lack of programming style rules, and software engineers with insufficient ability or experience.

  5. Label (computer science) - Wikipedia

    en.wikipedia.org/wiki/Label_(computer_science)

    In programming languages, a label is a sequence of characters that identifies a location within source code. In most languages, labels take the form of an identifier, often followed by a punctuation character (e.g., a colon). In many high-level languages, the purpose of a label is to act as the destination of a GOTO statement.

  6. Structured programming - Wikipedia

    en.wikipedia.org/wiki/Structured_programming

    While goto has now largely been replaced by the structured constructs of selection (if/then/else) and repetition (while and for), few languages are purely structured. The most common deviation, found in many languages, is the use of a return statement for early exit from a subroutine. This results in multiple exit points, instead of the single ...

  7. Control flow - Wikipedia

    en.wikipedia.org/wiki/Control_flow

    A label is an explicit name or number assigned to a fixed position within the source code, and which may be referenced by control flow statements appearing elsewhere in the source code. A label marks a position within source code and has no other effect. Line numbers are an alternative to a named label used in some languages (such as BASIC).

  8. Considered harmful - Wikipedia

    en.wikipedia.org/wiki/Considered_harmful

    The original title of the letter, as submitted to CACM, was "A Case Against the Goto Statement", but CACM editor Niklaus Wirth changed the title to "Goto Statement Considered Harmful". [6] Regarding this new title, Donald Knuth quipped that " Dr. Goto cheerfully complained that he was always being eliminated."

  9. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    [1] [2] Due to this, development tools for the two languages (such as IDEs and compilers) are often integrated into a single product, with the programmer able to specify C or C++ as their source language. However, C is not a subset of C++, [3] and nontrivial C programs will not compile as C++ code without modification. Likewise, C++ introduces ...
