Which data type can store largest value?
The smallest possible value of an ushort variable is 0; the largest possible value is 65,535. int: Holds 32-bit signed integers. The smallest possible value of an int variable is -2,147,483,648; the largest possible value is 2,147,483,647. uint: Holds 32-bit unsigned integers.
What is short data type in C?
short is short for short int . They are synonymous. short , short int , signed short , and signed short int are all the same data-type. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned. short int: -32767 to +32767 .
What is long in C?
Long. Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer. Therefore, if a variable or constant may potentially store a number larger than 2,147,483,647 (231 ÷ 2), it should be defined as a long instead of an int.
What are the 5 types of data?
PHP 5 Data Types
- Float (floating point numbers – also called double)
Which data type occupies least storage in C?
There are different data types in C associated to each variable and occupies different amount of memory. The char data type is used to store a single character and is the most basic data type in C. It requires only one byte of memory for storage and can contain both positive and negative values.
Which is the largest data type?
|int||32 bits||-2,147,483,648 .. 2,147,483,647|
|long||64 bits||-9,223,372,036,854,775,808 .. 9,223,372,036,854,775,807|
|float||32 bits||3.40282347 x 1038, 1.40239846 x 10-45|
|double||64 bits||1.7976931348623157 x 10308, 4.9406564584124654 x 10-324|

What are data types in C language?
Data types in C Language
- Primary data types: These are fundamental data types in C namely integer( int ), floating point( float ), character( char ) and void .
- Derived data types: Derived data types are nothing but primary datatypes but a little twisted or grouped together like array, stucture, union and pointer.
What is data type in C definition?
In the C programming language, data types are declarations for memory locations or variables that determine the characteristics of the data that may be stored and the methods (operations) of processing that are permitted involving them.
Is byte a data type in C?
Data Types in C. char: The most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers. int: As the name suggests, an int variable is used to store an integer. float: It is used to store decimal numbers (numbers with floating point value) with single precision.
What is double data type in C?
The C programming language provides four other basic data types: float, double, char, and _Bool. A variable declared to be of type float can be used for storing floating-point numbers (values containing decimal places). The double type is the same as type float, only with roughly twice the precision.
Is long a data type in C?
In C and C++, there are four different data type available for holding the integers i.e., short, int, long and long long. Each of these data type requires different amounts of memory. Well it also varies from compiler.
Which data type has more precision?
Both languages have the same set of three built-in floating-point types: float, double, and long double. Typically long double has greater precision and range than double (though there are implementations where they’re the same). (Some compilers might provide wider floating-point types as an extension.)
What are keywords in C?
Keywords are predefined, reserved words used in programming that have special meanings to the compiler. Keywords are part of the syntax and they cannot be used as an identifier. For example: int money; Here, int is a keyword that indicates ‘money’ is a variable of type integer.
What are the 4 types of data?
Types of Data & Measurement Scales: Nominal, Ordinal, Interval and Ratio. In statistics, there are four data measurement scales: nominal, ordinal, interval and ratio. These are simply ways to sub-categorize different types of data (here’s an overview of statistical data types) .
What are 2 types of data?
It is useful to distinguish between two broad types of variables: qualitative and quantitative (or numeric). Each is broken down into two sub-types: qualitative data can be ordinal or nominal, and numeric data can be discrete (often, integer) or continuous.
What are the examples of ratio scale?
The most common examples of ratio scale are height, money, age, weight etc. With respect to market research, the common examples that are observed are sales, price, number of customers, market share etc.
Which data type is most suitable for storing a number 65000 in a 32 bit system?
Which data type is most suitable for storing a number 65000 in a 32-bit system? Explanation: 65000 comes in the range of short (16-bit) which occupies the least memory. Signed short ranges from -32768 to 32767 and hence we should use unsigned short.
What is a short data type?
short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). long: The long data type is a 64-bit two’s complement integer.
What is void data type?
void data type in c. Generally void is an empty data type and it used as a return type of functions that return no value in c. Eg:-void func(int n) //It indicates that the function returns no result. Now the address of any variable of any data type such as char, int, and float can be assigned to a void pointer variable
What is data types and its types?
In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support common data types of real, integer and boolean.
What is data type explain its types?
Data Type. A data type is a type of data. When computer programs store data in variables, each variable must be assigned a specific data type. Some common data types include integers, floating point numbers, characters, strings, and arrays.
How do you find the range of data types in C?
printf(“\n%u to %u”, min, max);
- Convert the number of bytes into bits by multiplying the bytes with 8.
- range of int -2147483648 to 2147483647 range of unsigned int 0 to 4294967295 range of char -128 to 127 range of unsigned char 0 to 255 range of short -32768 to 32767 range of unsigned short 0 to 65535.
