  2. Maximal munch - Wikipedia

    en.wikipedia.org/wiki/Maximal_munch

    Another example, in C++, uses the "angle bracket" characters < and > in the syntax for template specialization, but two consecutive > characters are interpreted as the right-shift operator >>. [4] Prior to C++11, the following code would produce a parse error, because the right-shift operator token is encountered instead of two right-angle ...

  3. Pure function - Wikipedia

    en.wikipedia.org/wiki/Pure_function

    I/O is inherently impure: input operations undermine referential transparency, and output operations create side effects.Nevertheless, there is a sense in which a function can perform input or output and still be pure, if the sequence of operations on the relevant I/O devices is modeled explicitly as both an argument and a result, and I/O operations are taken to fail when the input sequence ...

  4. Template (C++) - Wikipedia

    en.wikipedia.org/wiki/Template_(C++)

    For example, if a program uses both an int and a double version of the max() function template above, the compiler will create an object code version of max() that operates on int arguments and another object code version that operates on double arguments.

  5. Associative containers (C++) - Wikipedia

    en.wikipedia.org/wiki/Associative_containers_(C++)

    A map, sometimes referred to as a dictionary, consists of a key/value pair. The key is used to order the sequence, and the value is somehow associated with that key. For example, a map might contain keys representing every unique word in a text and values representing the number of times that word appears in the text.

  6. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    For the purposes of these tables, a, b, and c represent valid values (literals, values from variables, or return value), object names, or lvalues, as appropriate. R, S and T stand for any type(s), and K for a class type or enumerated type. Some of the operators have alternative spellings using digraphs and trigraphs or operator synonyms.

  7. C date and time functions - Wikipedia

    en.wikipedia.org/wiki/C_date_and_time_functions

    computes the difference in seconds between two time_t values time: returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch). The value of the epoch is operating system dependent; 1900 and 1970 are often used. See RFC 868. clock

  8. Min-max heap - Wikipedia

    en.wikipedia.org/wiki/Min-max_heap

    Example of Min-max heap. Each node in a min-max heap has a data member (usually called key) whose value is used to determine the order of the node in the min-max heap. The root element is the smallest element in the min-max heap. One of the two elements in the second level, which is a max (or odd) level, is the greatest element in the min-max heap

  9. Multiple subset sum - Wikipedia

    en.wikipedia.org/wiki/Multiple_subset_sum

    For example, suppose Alice has two items with values 1 and e, for some small e>0. George has two items with value e. The capacity is 1. The maximum sum is 1 - when Alice gets the item with value 1 and George gets nothing. But the max-min allocation gives both agents value e. Therefore the POF is 1/(2e), which is unbounded. In both cases, if the ...
