  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.

  3. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    _Bool functions similarly to a normal integer type, with one exception: any assignments to a _Bool that are not 0 (false) are stored as 1 (true). This behavior exists to avoid integer overflows in implicit narrowing conversions. For example, in the following code: In C23, the boolean type was moved to bool, making the <stdbool.h> header now ...

  4. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.

  5. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    In addition to the assumption about bit-representation of floating-point numbers, the above floating-point type-punning example also violates the C language's constraints on how objects are accessed: [3] the declared type of x is float but it is read through an expression of type unsigned int.

  6. Comparison of programming languages (basic instructions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    ^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short, int, long, and (C99, C++11) long long, so they are implementation-dependent. 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.

  7. scanf - Wikipedia

    en.wikipedia.org/wiki/Scanf

    The formatting placeholders in scanf are more or less the same as that in printf, its reverse function.As in printf, the POSIX extension n$ is defined. [2]There are rarely constants (i.e., characters that are not formatting placeholders) in a format string, mainly because a program is usually not designed to read known data, although scanf does accept these if explicitly specified.

  8. Type signature - Wikipedia

    en.wikipedia.org/wiki/Type_signature

    Thus, calling f x, where f:: a-> b-> c, yields a new function f2:: b-> c that can be called f2 b to produce c. The actual type specifications can consist of an actual type, such as Integer , or a general type variable that is used in parametric polymorphic functions , such as a , or b , or anyType .
