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
maxis 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, andLoo.
Need for Function Templates
- Without function templates, a separate function
maxneeds 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
maxthat can work with different data types.
