The data type is essential to represent the type, nature and set of operations for the value which it stores. Floating-point number (e.g., 1.234) Integer (e.g., 1234) Long (e.g., 123456789) Short (e.g., 0) String (e.g., abcd) Void (e.g., no data) Depending on the programming language, there may also be many more data types that serve a specific function and store data in a particular way. In this example the first value is in fact not smaller than the second one, and the program therefore results in a Boolean value of False. Typically the index value of the first position is zero (0). This determines the type and size of data associated with variables. On most computer architectures a byte is made up of eight bits, each bit stores a one or a zero. -32,768 to 32,767 or -2,147,483,648 to 2,147,483,647, 1.2E-38 to 3.4E+38 till 6 decimal places. ; User defined data types are those data types which are defined by the user/programmer himself. Here is an example of how numeric values are used in code, in this case using a multiplication character: The value stored in the 'result' would be 353.67. Whenever a variable is defined in C++, the compiler allocates some memory for that variable based on the data-type with which it is declared. Subsequent chapters will show you how to use different data types in different situations. Each element has an index, which tells you at what position in the sequence that element is located. Some common ways to format dates are: Each programming language has some built-in tools to work with time - for example, to determine how long it took to carry out a particular calculation.
