WebC - Unions. A union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose. WebThe longest field in struct Info4 is short c, it will takes 2 bytes. So machine will use 2 bytes aligned strategy. The field char a, char b can store in the first 2-bytes space, and the short c will store in the second one. Totally, machine need to allocate 4 bytes. Similar to struct Info4, the longest field in struct Info5 is int c, it will ...

WebIf the array is a character array, then its elements will occupy 1 byte of memory each. If it is a float array then its elements will occupy 8 bytes of memory each. But this is not the total size or memory allocated for the array. They are the sizes of individual elements in the array. If we need to know the total size of the array, then we ... WebTo store double, computer will allocate 8 byte (64 bit) memory. Where, 1 bit for sign, 11 bit for exponent, 52 bit for significant. only difference between double and float representation is the bias value.

A Unicode character in UTF-32 encoding is always 32 bits (4 bytes). An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 – 16 bits. WebThe fundamental types in C are char (character), int (integer) and float. Some compilers include the bool data type. char char is the character type. The standard encoding scheme is ASCII. encoding schemes such as EBCDIC can be used. In C you can manipulate variables defined as character using the same operations that apply to integers. //
