What is a macro and why is it useful?

Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. (Thus, they are called “macros” because a “big” block of code can be expanded from a “small” sequence of characters.)

Macros can even accept arguments and such macros are known as function-like macros. It can be useful if tokens are concatenated into code to simplify some complex declarations.

What is macro and its types?
