| Type Name | Bytes | Range of Values |
|---|---|---|
| long | 4 | -2,147,483,648 to 2,147,483,647 |
| unsigned long | 4 | 0 to 4,294,967,295 |

What is the range of unsigned int in C?
0 to 4294967295
A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a nonnegative integer in the range [0 to 4294967295].
What is unsigned long in C?
Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes). Unlike standard longs unsigned longs won’t store negative numbers, making their range from 0 to 4,294,967,295 (2^32 – 1).
What is is the value range of unsigned int?
In 32-bit integers, an unsigned integer has a range of 0 to 2^32 -1 = 0 to 4,294,967,295 or about 4 billion.
Is Long Long always 64 bit?
@pmg long long also guarantees at least 64 bits.
What is unsigned long long?
An unsigned version of the long long data type. An unsigned long long occupies 8 bytes of memory; it stores an integer from 0 to 2^64-1, which is approximately 1.8×10^19 (18 quintillion, or 18 billion billion). A synonym for the unsigned long long type is uint64 .
Is Long Long always 64-bit?
Is long int 64 bit?
int is 32 bits in size. long , ptr , and off_t are all 64 bits (8 bytes) in size.
What is long long int?
A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. This doesn’t necessarily mean that a long long is wider than a long . Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide.
Is Long signed or unsigned?
long: The long data type is a 64-bit two’s complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.
What is unsigned long long int in C++?
In this article, we will discuss the unsigned long long int data type in C++. It is the largest (64 bit) integer data type in C++. It takes a size of 64 bits. A maximum integer value that can be stored in an unsigned long long int data type is 18, 446, 744, 073, 709, 551, 615, around 264 – 1(but is compiler dependent).
What is the range of long long in C++?
Long
| Data Type | Size (in bytes) | Range |
|---|---|---|
| short int | 2 | -32,768 to 32,767 |
| long int | 4 | -2,147,483,648 to 2,147,483,647 |
| unsigned long int | 8 | 0 to 4,294,967,295 |
| long long int | 8 | -(2^63) to (2^63)-1 |
What is the difference between int and unsigned int?
As the names imply, int is a signed integer type, and unsigned int is an unsigned integer type. That means that int is able to represent negative values, and unsigned int can represent only non-negative values.
What is the maximum value of an unsigned integer?
Modern computers almost universally use 2’s complement arithmetic, which means that a signed integer of n bits width has a minimum value of – (2^N-1) and a maximum value of (2^N-1)-1. Unsigned integers have a minimum value of 0 and a maximum value of 2^N-1. So the maximum unsigned integer values for 16 and 32 bit sizes are the numbers given above.
What is the difference between int and long?
The basic difference between the type int and long is of their width where int is 32 bit, and long is 64 bits. The types int and long when counted in bytes instead of bits the type int is 4 bytes and the type long is just twice if type int i.e. 8 bytes.
What is an unsigned integer?
unsigned integer. [ən′sīnd ′int·ə·jər] (mathematics) A whole number that is equal to or greater than zero and does not carry a positive or negative sign.
