  2. Control table - Wikipedia

    en.wikipedia.org/wiki/Control_table

    To make a selection in the example above, the average instruction path length (excluding the subroutine code) is '4n/2 +3', but can easily be reduced, where n = 1 to 64, to a constant time with a path length of '5' with zero comparisons, if a 256 byte translate table is first utilized to create a direct index to CT1 from the raw EBCDIC data ...

  3. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

  4. Ternary conditional operator - Wikipedia

    en.wikipedia.org/wiki/Ternary_conditional_operator

    The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...

  5. Common subexpression elimination - Wikipedia

    en.wikipedia.org/wiki/Common_subexpression...

    In compiler theory, common subexpression elimination (CSE) is a compiler optimization that searches for instances of identical expressions (i.e., they all evaluate to the same value), and analyzes whether it is worthwhile replacing them with a single variable holding the computed value. [1]

  6. Inclusion–exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Inclusion–exclusion...

    Each value represents the set of shuffles having at least p values m 1, ..., m p in the correct position. Note that the number of shuffles with at least p values correct only depends on p, not on the particular values of . For example, the number of shuffles having the 1st, 3rd, and 17th cards in the correct position is the same as the number ...

  7. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    This is a list of operators in the C and C++ programming languages.. All listed operators are in C++ and lacking indication otherwise, in C as well. Some tables include a "In C" column that indicates whether an operator is also in C. Note that C does not support operator overloading.

  8. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    That is, a statement such as x = expression; (i.e. the assignment of the result of an expression to a variable) clearly calls for the expression to be evaluated and the result placed in x, but what actually is in x is irrelevant until there is a need for its value via a reference to x in some later expression whose evaluation could itself be ...

  9. Comparison of Pascal and C - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Pascal_and_C

    The code in braces will always execute because the assignment expression a = 10 has the value 10 which is non-zero and therefore considered "true" in C; this is in part because C (and ALGOL) allow multiple assignment in the form a = b = c = 10; which is not supported by Pascal.
