Functions

In Cangjie, the keyword func is used to denote the start of a function definition. Following func are the function name, parameter list, optional return type, and function body. The function name can be any valid identifier. The parameter list is enclosed in parentheses (with multiple parameters separated by commas), a colon separates the parameter list and the return type (if present), and the function body is enclosed in curly braces.

Example of a function definition:

In the above example, a function named add is defined. Its parameter list consists of two Int64 parameters, a and b, and its return type is Int64. The function body adds a and b together and returns the result.
