Definition of Quatrain. A quatrain is a stanza in a poem that has exactly four lines. Some quatrains comprise entire poems, while others are part of a larger structure. Quatrains usually use some form of rhyme scheme, especially the following forms: AAAA, AABB, ABAB, and ABBA.
Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to variables, you can store integers, decimals, or characters in these variables. There are two data types available in Java â.
C# has two types of variables: value and object.. Variables of object type are stored on the heap. Value type variables are not. Value type variables behave rather like native variables in C++ (types like int), except that they are classes, and the values that are assigned to them are classes or structs. The way you can tell the difference between the two is that value type variables can take a literal.
