Identifier variables are categorical variables that have a single individual per category. For example: A Social Security Number. Interviewer ID number.
A Variable is a name that is assigned to a memory location, which is used to contain the corresponding value in it. Variables are only the sort of identifiers. It strictly prohibited to have the same of two or more identifiers. It Ex's: are Structure name, Function name, Class, Enumerator name, Union, etc.
All C++ variables must be identified with unique names. These unique names are called identifiers. Identifiers can be short names (like x and y) or more descriptive names (age, sum, totalVolume).
Python variable is also known as an identifier and used to hold value. In Python, we don't need to specify the type of variable because Python is a infer language and smart enough to get variable type. Variable names can be a group of both the letters and digits, but they have to begin with a letter or an underscore.
I'm a bit confused about identifiers. In my textbook it says, "We use identifiers to name variables (and many other things) in Java."
I'm not really sure what this means. Is it like assigning a variable...to a variable? What?
So far, I'm getting this impression:
int a, b, c; a = 2; b = 99; c = a + b; Is c an identifier? When it says, "Using identifiers to name variables," are identifiers like int, double, boolean, things used to categorize variables? Please provide some examples.
