    Those are types. Variables are whatever you want as long as the name isn't a reserved word.

    >but can i type a full sentences as a Variables?
    You can, but you need to get creative in separating the words of the sentence:
    Code:
    double some_long_variable_name_that_represents_a_double;
    My best code is written with the delete key.

    TYPE - MINIMUM SIZE (BYTES)
    char - 1
    unsigned char - 1
    int - 2
    unsigned int - 2
    short - 2
    unsigned short - 2
    long - 4
    unsigned long - 4

    float - 4
    double - 8

    but can i type a full sentences as a Variables?
    Do you mean, "Can a variable hold a sentence?" No. A single variable can only hold a single character. You need an array of characters to hold a word or sentence. See the array and string tutorials. C++ also has a string class which can sometimes be used more like a single variable.

    in general programming terminology, string means "a string of characters". In C++, a character array is often called a c-style string to differentiate it from a C++ string class object.
