The maximum value of N is provided by BITINT_MAXWIDTH and is at least ULLONG_WIDTH. Therefore, the type _BitInt (2) (or signed _BitInt (2)) takes values from −2 to 1 while unsigned _BitInt (2) takes values from 0 to 3. The type unsigned _BitInt (1) also exists, being either 0 or 1 and has no equivalent signed type. [13]
Instead, numeric values of zero are interpreted as false, and any other value is interpreted as true. [9] The newer C99 added a distinct Boolean type _Bool (the more intuitive name bool as well as the macros true and false can be included with stdbool.h), [10] and C++ supports bool as a built-in type and true and false as reserved words. [11]
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 C++03. For an ANSI/ISO compliant compiler, the minimum requirements for the specified ranges, that is, −(2 63 −1) [ 11 ] to 2 63 −1 for signed and 0 to 2 64 −1 for unsigned, [ 12 ...
Load the element with type unsigned int8 at index onto the top of the stack as an int32. Object model instruction 0x93 ldelem.u2: Load the element with type unsigned int16 at index onto the top of the stack as an int32. Object model instruction 0x95 ldelem.u4: Load the element with type unsigned int32 at index onto the top of the stack as an int32.
A record is a value that contains other values, typically in fixed number and sequence and typically indexed by names. The elements of records are usually called fields or members. An object contains a number of data fields, like a record, and also offers a number of subroutines for accessing or modifying them, called methods.
Consequently, the construct sizeof (char) is guaranteed to be 1. The actual number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the standard include file limits.h. On most modern computing platforms this is eight bits. The result of sizeof has an unsigned integer type that is usually denoted by size_t.
The primary facility for accessing the values of the elements of an array is the array subscript operator. To access the i-indexed element of array, the syntax would be array[i], which refers to the value stored in that array element. Array subscript numbering begins at 0 (see Zero-based indexing). The largest allowed array subscript is ...
Applications that were display-intensive typically used to access CGA video memory directly by casting the hexadecimal constant 0xB8000 to a pointer to an array of 80 unsigned 16-bit int values. Each value consisted of an ASCII code in the low byte, and a colour in the high byte. Thus, to put the letter 'A' at row 5, column 2 in bright white on ...
