Can variables have more than one value at a time?
A variable holds more than one value if you declare it to be of a composite data type. Composite Data Types include structures, arrays, and classes. A variable of a composite data type can hold a combination of elementary data types and other composite types. Structures and classes can hold code as well as data.
How many items of data can a variable store?
The most simple form of storage is called a variable. It's an area of memory that stores one item of data, such as a number or a character.
What is variable that holds one value at a time?
1 Answer. The explanation is: A scalar variable was a variable which holds one value at a time. It is a single component which assumes a range of number or string values.
How many values can a variable store at one time Python?
one value Each time through the loop it holds a different value. But just one value at a time. Variables can only refer to a single object at a time. That object can be a container of some sort, a list , tuple etc, but it is always referring to a single object.
Can store one or more values in a single variable name?
array An array in Java is used to store multiple values in a single variable, instead of declaring separate variables for each value. In other words, an array is a collection of elements stored in what can be described as a list.
Which special variable hold more than one value at a time?
Solution. An array is a variable, which can hold more than one value at a time.
What a variable is?
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
What is a memory variable?
A variable is the name of a memory cell. It is "variable" because the value in the cell can change. Each memory cell has an address. Python and other high-level languages use a symbol table to map a variable name to the address it represents.
Which can hold more than one value at a time?
Solution. An array is a variable, which can hold more than one value at a time.
How do I store multiple values in one variable?
An array in Java is used to store multiple values in a single variable, instead of declaring separate variables for each value. Therefore, an array is a collection of fixed elements in what can be seen as a list. Each element in an array consists of the same data type and can be retrieved and used using its index.
How large can a Python variable be?
Technicality: note that it's not a “variable”; Python doesn't have any, more or less. You want the maximum size of an object; what you call “variables” are names of objects.
Can a variable have multiple values Python?
You can assign multiple values to multiple variables by separating variables and values with commas , . You can assign to more than three variables. It is also possible to assign to different types. If there is one variable on the left side, it is assigned as a tuple.
How do you store multiple values in one variable?
With JavaScript array variables, we can store several pieces of data in one place. You start an array declaration with an opening square bracket, end it with a closing square bracket, and put a comma between each entry, like this: var sandwich = ("peanut butter", "jelly", "bread").
Can a variable hold multiple values in Java?
An array in Java is used to store multiple values in a single variable, instead of declaring separate variables for each value. Therefore, an array is a collection of fixed elements in what can be seen as a list. Each element in an array consists of the same data type and can be retrieved and used using its index.
Can only hold one member value at a time?
A union is a user-defined type similar to structs in C except for one key difference. Structures allocate enough space to store all their members, whereas unions can only hold one member value at a time.
What is the value of a variable?
Definition: A variable is a holder for a representation of a value. A variable does have location in time and space. Also, variables, unlike values, can be updated; that is, the current value of the variable can be replaced by another value.
What is variable number?
Number variables are also known as integer or Int32, and are used to store numeric information. They can be used to perform equations or comparisons, pass important data and many others.
How variables are stored?
Variables are usually stored in RAM. This is either on the heap (e.g. all global variables will usually go there) or on the stack (all variables declared within a method/function usually go there). Stack and Heap are both RAM, just different locations.
Why are variables called variable?
Variables are called variables because they vary, i.e. they can have a variety of values. Thus a variable can be considered as a quantity which assumes a variety of values in a particular problem.
Can a variable have two values in Python?
You can assign multiple values to multiple variables by separating variables and values with commas , . You can assign to more than three variables. It is also possible to assign to different types. If there is one variable on the left side, it is assigned as a tuple.
How do you store data in one variable?
0:004:55Store Multiple Values in one Variable using JavaScript Arrays – YouTubeYouTube
Can a variable have multiple values JavaScript?
There is no way to assign multiple distinct values to a single variable. An alternative is to have variable be an Array , and you can check to see if enteredval is in the array. To modify arrays after you have instantiated them, take a look at push , pop , shift , and unshift for adding/removing values.
How big can a variable be?
How Big Is a Variable. As big as is needed and no more. The smallest a variable can be is one bit and the largest is millions of bytes. Current processors handle data in chunks of 4 or 8 bytes at a time (32 and 64 bit CPUs), so the bigger the variable, the longer it will take to read or write it.
How many digits can Python handle?
The pythonic way Similarly for python, "digit" is in base 2³⁰ which means it will range from 0 to 2³⁰ – 1 = 1073741823 of the decimal system.
How do I put multiple values in one variable?
You can assign the same value to multiple variables by using = consecutively. This is useful, for example, when initializing multiple variables to the same value. It is also possible to assign another value into one after assigning the same value.
Can a variable have more than one value JavaScript?

Are variables and values the same?
Interpretations: "value": it is the actual data or instructions stored in computer. "variable": it is a way locating the data, a value-replacing reference , but not itself the set of data or instruction stored in computer.
