  2. Undefined behavior - Wikipedia

    en.wikipedia.org/wiki/Undefined_behavior

    [17] [18] The following example will cause undefined behavior in both C and C++. int f ( int i ) { return i ++ + i ++ ; /* undefined behavior: two unsequenced modifications to i */ } When modifying an object between two sequence points, reading the value of the object for any other purpose than determining the value to be stored is also ...

  3. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    Language Unsigned integer Signed integer Ada: modulo the type's modulus: raise Constraint_Error: C, C++: modulo power of two: undefined behavior C#: modulo power of 2 in unchecked context; System.OverflowException is raised in checked context [10] Java: modulo power of two (char is the only unsigned primitive type in Java) modulo power of two ...

  4. 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).

  5. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The C language provides the four basic arithmetic type specifiers char, int, float and double (as well as the boolean type bool), and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations.

  6. Uninitialized variable - Wikipedia

    en.wikipedia.org/wiki/Uninitialized_variable

    Uninitialized variables are a particular problem in languages such as assembly language, C, and C++, which were designed for systems programming. The development of these languages involved a design philosophy in which conflicts between performance and safety were generally resolved in favor of performance.

  7. Integer (computer science) - Wikipedia

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

    In the C99 version of the C programming language and the C++11 version of C++, a long long type is supported that has double the minimum capacity of the standard long. This type is not supported by compilers that require C code to be compliant with the previous C++ standard, C++03, because the long long type did not exist in

  8. Comparison of programming languages (basic instructions)

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

    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. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...

  9. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    Java does not feature unsigned integer types. In particular, Java lacks a primitive type for an unsigned byte. Instead, Java's byte type is sign extended, which is a common source of bugs and confusion. [18] Unsigned integers were left out of Java deliberately because James Gosling believed that programmers would not understand how unsigned ...
