# Variables
Variables can be defined in the global scope, in structs and classes, and in functions.

## Global variables
Global variables can be defined as such:

```c2
// Defines a global variable called my_var.
int32 my_var;

// Defines a const variable.
const int32 my_var;

// Defines a global variable whose type is determined automatically.
// The value will be determined at runtime.
var my_var = 123;

// Defines a const variable whose type is determined automatically.
const my_var = 123;

// Defines a global variable whose initial value is computed at compile-time.
// If it cannot be computed at compile-time, an error is thrown.
static my_var = 123;
```
