WebThe size is typically about 32-bits or 4 bytes on a 16/ 32-bit compiler. Yet, it varies depending on what compiler we are using. There is no specification of the data types sizes according to the C standard, except the character. According to the definition by C: Every compiler can choose an appropriate size for hardware of its own. WebIf 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 need to multiply the number of elements with the size of individual element.

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. 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. onsitex
