An integer stores a whole number. The exact range depends on the language; in Java, "int" stores whole numbers in a range of approximately minus 2 billion to plus to billion.
A boolean variable, on the other hand, stores only one of two values - these are often called "true" and "false" (as in Java). Boolean variables are often used to keep track of information that can be thought of as a reply to a "yes/no" question. For example, to mark whether a certain item is active or not you have only two choices, so it makes sense to use a boolean variable.
Instantiation is creating the instance of the variable/object . While Initialization is to provide the variable with some value. int i; // i is an instance of an integer i=10; //initialised with the value 10
A variable has a data type such as integer, string, double. A data type tells the variable to only store values that are a particular data type, so you can only store numbers without decimal points in an integer variable, and only characters such as "ABCD" in a string variable.
You cannot. An Integer is a numeric value whereas a boolean array list is a collection of a number of true or false values. So, you cannot convert either into the other
with an assignment: variable = value variable += value variable /= -3; ...
Variables define a certain value, such as an integer, string, boolean value, etc. Functions are defined to run a certain task, and may or may not return a value. You can have a function that calculates the sum of two numbers and returns the sum once calculated.
The set of the possible values.
Boolean means yes or no, true or false, 0 or 1. There can only be 2 alternatives in boolean. In JavaScript there is a function typeof which will show whether variable is boolean, string, integer or any other. I am providing a few examples. Try those and you will understand what type of variable is providedvar a = 12;alert("Variable is of type: "+typeof(a));var a = "hello";alert("Variable is of type: "+typeof(a));
No
Declaration is basically defining data type and length and assignment is to assign the value. Below is the declaration -- var a integer /* this means we are declaring a variable a as integer data type */ a= 5 /* this is assignment,we are assigning 5 to variable a */

an integer is a whole number
sometimes
no, you cant. it only works on string

The difference between any numbers is always positive.
In programming, the term "prefix" typically refers to a naming convention that precedes the name of a variable. Common prefixes include "int" for integer variables, "str" for string variables, "bool" for boolean variables, and so on. These prefixes help developers quickly identify the data type of a variable.
