    What is data type in C language?

    In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations or variables. Data types also determine the types of operations or methods of processing of data elements.

    What is data type in C++ with example?

    example: int, char , float, bool etc. Primitive data types available in C++ are: Integer….Long.

    Data Type	Size (in bytes)	Range
    short int	2	-32,768 to 32,767
    long int	4	-2,147,483,648 to 2,147,483,647
    unsigned long int	8	0 to 4,294,967,295
    long long int	8	-(2^63) to (2^63)-1

    What is data type and explain its types?

    A data type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support various types of data, including integer, real, character or string, and Boolean.

    What are the different data types in GCC?

    double: It is used to store decimal numbers (numbers with floating point value) with double precision. Different data types also have different ranges upto which they can store numbers. These ranges may vary from compiler to compiler. Below is list of ranges along with the memory requirement and format specifiers on 32 bit gcc compiler.
