In this lesson we see the declaration and assignment of variables. You can also assign a value at the same time. D allows you to declare multiple variables of the same type in the same line. If you write: i, j, and k are all declared as ints but only k is assigned 30. It is the same as:

In D, variables can be explicitly declared with a type, or you can use auto for type inference. You can declare multiple variables of the same type in one line. D performs type inference when you use auto or initialize a variable.

Variables in the D programming language are defined by declaring a data type, followed by a variable name and optionally assigning an initial value. Below is a detailed explanation with key concepts and an example:

Learn about variables in D programming, including declaration, initialization, and types. Understand how to effectively use variables in your D code.

Apr 19, 2020 · A variable is the association of a name with a value of a particular type. This is done so that we can store values and retrieve them later on in a program. To be more technical about it, the name is a pointer to a memory address that holds the value. The type declaration forces the value to fit into a certain number of bytes.

D inherits from C and C++ in its basic style of variable initialization. For example: declares a variable named x of type int, whose initial value is 10. However, because D has static type inference, there is often no need to explicitly specify the type of the variable: declares an int variable named x, whose initial value is 10.

Local variables in functions declared as static, shared static or __gshared are statically allocated rather than being allocated on the stack. The lifetime of __gshared and shared static variables begins when the function is first executed and
