How much data can a variable hold?
Character variables hold a single byte and are used for holding the 256 characters and symbols of the ASCII and extended ASCII character sets.
How much value can a variable hold at a time?
one value A variable can only store one value at a time – a number or a string. A value stored in a variable can be used once or many times in a program.
How much data can a python variable store?
If you want to store a number larger than 2,147,483,647, Python can do it, using the long int data type. Rather than allocating a fixed four bytes of memory for a long int variable, Python decides how many bytes to assign based on the actual size of the number.
What two things does a variable declaration specify about a variable?
A variable declaration always contains two components: the type of the variable and its name. Also, the location of the variable declaration, that is, where the declaration appears in relation to other code elements, determines the scope of the variable.
What is variable data?
Variable data is defined as information and figures used to build control charts. Variable data can be used to create average (X-bar) charts, range charts, and sample standard deviation charts or "S-charts."
What is the size of data type?
Data Types and Sizes
| Type Name | 32–bit Size | 64–bit Size |
|---|---|---|
| char | 1 byte | 1 byte |
| short | 2 bytes | 2 bytes |
| int | 4 bytes | 4 bytes |
| long | 4 bytes | 8 bytes |
Can a variable hold more than one value?
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.
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 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.
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.
How many variable of the same data type can be declared in a single declaration statement?
you cannot declare more than one variable of Same data type using a single statement at the time of initialisation
What type of data does the variable contain?
A variable that contains quantitative data is a quantitative variable; a variable that contains categorical data is a categorical variable….Categorical variables.
| Type of variable | What does the data represent? | Examples |
|---|---|---|
| Nominal variables | Groups with no rank or order between them. | Species names Colors Brands |

Is variable data continuous?
A variable is said to be continuous if it can assume an infinite number of real values within a given interval. For instance, consider the height of a student. The height can't take any values. It can't be negative and it can't be higher than three metres.
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.
How many digits can an integer hold?
10 digits The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision.
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.
Which kind of variables can hold several values and types at one time?
An array is a variable, which can hold more than one value at a time.
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.
Can a variable be 2 values?
A variable can be an object which can hold two or more fields/values.
What is variable memory?
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.
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 much data can a string hold in Python?
With a typical 32-bit Python installation, the total memory you can use in your application is limited to something like 2 or 3 GB (depending on OS and configuration), so the longest strings you can use will be much smaller than in 64-bit installations with high amounts of RAM.
Can a variable have multiple declarations?
While declaration memory is not allocated to the variable. A variable can be declared multiple times. Definition is the super-set of declaration. Variable definition means that a variable is declared and memory is allocated to that variable.
Can variables have numbers?
After the first initial letter, variable names can also contain letters and numbers. No spaces or special characters, however, are allowed.
How many variables do we have?
There are two types of quantitative variables: discrete and continuous….Quantitative variables.
| Type of variable | What does the data represent? | Examples |
|---|---|---|
| Continuous variables (aka ratio variables) | Measurements of continuous or non-finite values. | Distance Volume Age |

What type of variable is time?
Continuous variable: a variable with infinite number of values, like “time” or “weight”.
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 do variables work?
A variable is a symbolic name for (or reference to) information. The variable's name represents what information the variable contains. They are called variables because the represented information can change but the operations on the variable remain the same.
What is the size of an integer variable?
Data Types and Sizes
| Type Name | 32–bit Size | 64–bit Size |
|---|---|---|
| short | 2 bytes | 2 bytes |
| int | 4 bytes | 4 bytes |
| long | 4 bytes | 8 bytes |
| long long | 8 bytes | 8 bytes |
Can a variable hold multiple values?
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.
