A variable in a programming language is a memory space allocated to store values. You can use variables to store different types of values that include integer, character, factor, float, matrices, and tables. The scope of a variable defines the accessibility of the variable within a program. ...
An argument is a way for you to provide more information to a function. The function can then use that information as it runs, like a variable. Said differently, when you create a function, you can pass in data in the form of an argument, also called a parameter. ...
A variable is an identifier that refers to the data item stored at a particular memory location. This data item can be accessed in the program simply by using the variable name. The value of a variable can be changed by assigning different values to it a
In short, a value is some assigned meaning to a variable (the object containing the value) For example type=boolean; name=help; variable=a storage location; value=what is stored in that location; Further break down: X = 2; where X is a variable while 2 is the value stored in X. ...
