What is a Data Type?
A datatype is a classification that defines the type of data a variable can hold in programming. It specifies the kind of values that a variable can take, such as integers, floating-point numbers, characters, or boolean values. Datatypes help ensure data integrity and enable the compiler or interpreter to allocate appropriate memory space. They also determine the operations that can be performed on the data. For example, arithmetic operations are applicable to numerical datatypes, while string manipulation is reserved for character datatypes. Choosing the right datatype is crucial for efficient storage and manipulation of data in computer programs.
