  2. Type conversion - Wikipedia

    en.wikipedia.org/wiki/Type_conversion

    In computer science, type conversion, [1] [2] type casting, [1] [3] type coercion, [3] and type juggling [4] [5] are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa.

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    Any user-defined conversion must be explicitly marked as explicit or implicit, unlike C++ copy constructors and conversion operators, which are both implicit by default. C# has explicit support for covariance and contravariance in generic types, [ 16 ] : 144 [ 20 ] : 23 unlike C++ which has some degree of support for contravariance simply ...

  5. Integer literal - Wikipedia

    en.wikipedia.org/wiki/Integer_literal

    In computer science, an integer literal is a kind of literal for an integer whose value is directly represented in source code.For example, in the assignment statement x = 1, the string 1 is an integer literal indicating the value 1, while in the statement x = 0x10 the string 0x10 is an integer literal indicating the value 16, which is represented by 10 in hexadecimal (indicated by the 0x prefix).

  6. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    C++ is also more strict in conversions to enums: ints cannot be implicitly converted to enums as in C. Also, enumeration constants (enum enumerators) are always of type int in C, whereas they are distinct types in C++ and may have a size different from that of int. [needs update] In C++ a const variable must be initialized; in C this is not ...

  8. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    In C and C++, constructs such as pointer type conversion and union — C++ adds reference type conversion and reinterpret_cast to this list — are provided in order to permit many kinds of type punning, although some kinds are not actually supported by the standard language.

  9. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    In both C# and Java, programmers can use enumerations in a switch statement without conversion to a string or primitive integer type. However, C# disallows implicit fall-through unless the case statement does not contain any code, as it is a common cause of hard-to-find bugs. [29] Fall-through must be explicitly declared using a goto statement ...
