# What is a long int C++?

**long**. Type

**long**(or

**long int**) is an integral type that is larger than or equal to the size of type

**int**. (On Windows

**long**is the same size as

**int**.) Objects of type

**long**can be declared as

**signed long**or

**unsigned long**.

Similarly, you may ask, how big is an int C++?

Long

Data Type | Size (in bytes) | Range |
---|---|---|

short int | 2 | -32,768 to 32,767 |

unsigned short int | 2 | 0 to 65,535 |

unsigned int | 4 | 0 to 4,294,967,295 |

int | 4 | -2,147,483,648 to 2,147,483,647 |

Subsequently, question is, is Long Long same as 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** .

Beside this, what does int mean in C++?

An **int** variable contains only whole numbers **Int**, short for "integer," is a fundamental variable type built into the compiler and used to define numeric variables holding whole numbers. Other data types include float and double. C, **C++**, C# and many other programming languages recognize **int** as a data type.

What is unsigned long long int?

Description. **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).
