An identifier is simply the name of something, while a variable is an instance of something.
For example:
int x;
Here, the identifier is "x," but the variable is the object whose name is "x." A: An identifier is a name of something. Typically used in computer programming, the term "identifier" is frequently used to name a variable (see below), a subroutine, are in reality, any place in memory in which data or code reside where a name would be useful. "MyBirthDate" might be a good identifier, pointing to a memory location where the data contianing your date of birth is stored. The term variable comes to us from mathematics, but is frequently used in computer science too. It refers to a value that varies. For instance: a + b = 5 In this case, the value of a and b can change, so long as the sum of a and b equal 5. The opposite of the term variable is constant. In the equation, E=Mc2, c is a constant that is equal to the speed of light in a vacu -- +- 186,000 miles per second. In computer science, the term "variable" is used synonymously with "identifier" when they are both used to point to memory that contains data that may be changed and will not always be the same. In Microsoft BASIC, the statement: Tomorrow = Today + 1 Today and Tomorrow are variables, and 1 is a constant.
Identifier:The words formed in language C is termed as an identifier.
Variable: A variable is an entity whose can change during program execution.
Yes.
difference between constant and static variables in java
No. Identifier is a scientific name for the name.Variables, functions, types, etc -- each have an identifier.
If you mean a variable name, then no -- it must begin with a letter or an underscore, but any combination of letters, digits and underscores may follow. If you mean a variable that stores an identifier, then yes -- so long as the identifier is a string type.
It refers to a place in your code where names or variable have meaning.
The structure tag is a type. The structure variable is an instance of that type.
a variable having the datattype and name, an identifier is the name of the variable for example int x; here int x; is the variable x is the identifier
No, the name of the variable is its identifier.
yes.
Answer:- identifier is the name like a, b, c, .... which is used to reference a memory location in a program. +-variable is the actual memory location which can hold values.so 'a' is an identifier to a variable which is memory location located somewhere in memory.Answer:A Variable in Java is something that holds a particular value in a class. For example:public class A { private String name = ""; ......} In the above declaration name is a variable. It would hold the data of type String.An Identifier is nothing but the name that we give for our variables, classes, methods etc. It is nothing but the name with which we identify an entity in Java. For example here A is the identifier for the class, name is the identifier for the variable etc.
difference between fixed and variable inputs
a -- identifier 'a' -- character-literal "a" -- string-literal
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
difference between constant and static variables in java
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
No. Identifier is a scientific name for the name.Variables, functions, types, etc -- each have an identifier.
The variable.
