User Defined DataType

The data type is a format to store data that contains a particular range or type of value. It specifies which type of value a variable should have. In other words, a data type describes the type of data that variables can store. When a program stores data in the variables, then every variable needs to be assigned value that falls within the range of its data type. The following are some of the data types:
