In The Programming Language C#, How Do Int, Int16, Int32, And Int64 Differ From Each Other?

In C#, int, Int16, Int32, and Int64 are pre-defined data types used to represent different sizes of integer values. The key differences between them lie in their size and the range of values they can hold. Here’s a breakdown:

  1. int: Also known as System.Int32, it is a 32-bit signed integer type, which means it can store whole numbers between approximately -2 billion and +2 billion (-2,147,483,648 to 2,147,483,647). This is the most commonly used integer type in C#.

  2. Int16: Also known as short or System.Int16, it is a 16-bit signed integer type, capable of storing whole numbers ranging from approximately -32,000 to +32,000 (-32,768 to 32,767). It takes up half the memory of an int but has a smaller range of values.

  3. Int32: This is just another name for int. It is an alias defined for System.Int32 data type.

  4. Int64: Also known as long or System.Int64, it is a 64-bit signed integer type. It can store larger whole numbers compared to int, with a range of approximately -9 quintillion to +9 quintillion (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807). It uses twice the memory of an int but offers a much wider range of values.

In general usage, int is the default choice for integer values, especially when the value range stays within its limits. However, if you require a larger range of values, you can use Int64 (long) or Int16 (short) based on your specific needs.
