Summary. Even if you skimmed the lot - all you really need to know is that Func<T, bool> is a pointer to a compiled delegate method and Expression<Func<T, bool>> is a description of a function that can be compiled to IL at runtime or translated into whatever language we have a provider for.

A void function does not return a value to its caller. Functions are subprograms that do not execute until they are called. Value returning functions are used when only one result is returned and that result is used directly in an expression.

4 Answers. Macros are handled by the pre-processor - the pre-processor does text replacement in your source file, replacing all occurances of 'A' with the literal 8. Constants are handled by the compiler. They have the added benefit of type safety.

All you need to do is pass it the full filename as a string, and the macro returns either True (if the file exists) or False (if it doesn't). This function works by using the Dir function, which checks for a file in a directory. If the file exists, then Dir returns the full path of the file.

There are two kinds of subprograms in Ada, functions and procedures. The distinction between the two is that a function returns a value, and a procedure does not. In this example, we see that parameters can have default values. When calling the subprogram, you can then omit parameters if they have a default value.
