    Study Notes

    What is Metaprogramming?

    • Metaprogramming is a programming paradigm that involves writing programs that can manipulate, generate, or modify other programs

    What is a Program?

    • A program is a set of instructions that a computer can execute to solve a problem
    • Programs consist of algorithms and data structures
    • A program takes input data, processes it, and produces output data

    What is Programming?

    • Programming is the human activity of writing programs for a computer system
    • Programs need to be transformed into executable specifications that can be interpreted by a computer
    • Executable specification refers to a sequence of computations that can be executed by a microprocessor

    Problems of Programming

    • Manual coding is a labor-intensive task
    • Repetitive coding can be inefficient
    • Traditional typing systems can be difficult to adapt and reuse

    Function Templates

    • Function templates are needed to address the problems of programming

    • Function templates allow for implicit use of argument types

    • However, function templates have limitations, such as requiring specification and implementation to be in the same file### Function max

    • The function max is used to find the maximum value between two parameters.

    • The function is defined multiple times for different data types, such as int, float, Hoo, Moo, Doo, Noo, Foo, Poo, Boo, Koo, Joo, Knafn, Ioo, Coo, Goo, and Loo.

    Need for Function Templates

    • Without function templates, a separate function max needs to be defined for each data type.
    • This leads to code duplication and makes the code less maintainable.
    • Function templates provide a way to define a single function max that can work with different data types.
