If you have never learned about programming before, you might be wondering what it is for. Most computer experts describe programming as a collection of English language containing a list of instructions given to a computer.
In this modern world, programming is useful almost in everything. It has power over technologies and innovations that are controlled by programs. Examples of technology created through programming include robots, self-driving cars, 3-D animated movies, websites, games, and applications. Moreover, programming has different styles in which programmers could use to invent a wide variety of useful software. And one of these styles is generic programming.
Defining What Algorithm Means
To be able to understand what generic programming is, we need to know first what the term algorithm means. The algorithm is a step by step process intended for the computer program to accomplish a specific task. It usually begins with the word start and ends with the word stop. For example, listing a step by step procedure on how Google hangouts convey actual videos across the internet.
In the context of non-computer related experts, generic programming is a term synonymous to the recipe. For example, listing a step by step procedure towards making grilled chicken strips. Of course, algorithms in computer science are relatively more complex than our everyday algorithms.
But by applying the right type of algorithm, a programmer saves effort and makes your program faster. The searching algorithm, sorting algorithm, recursive algorithm and graph algorithm are one of the types programmers can use in generic programming.
Generic Programming And The Different Languages
Generic programming is a model comprised of a sequence of program instructions that performs a detailed task which works on not just one but all forms of data types. It is also about separating and organizing algorithms and data structures to achieve a gradual creation of efficient records. In this style of programming, programmers transform the general instruction into specific ones in a later time.
In generic programming, programmers use different language approaches since it supports programming patterns or paradigm. The first one is the object-oriented programming language which has specific virtual functions and conditions. It is a model wherein the programmers can view the organized flow of objects and data. It means there is no need to write a new code for a data type because this language types less. A famous example of this is the Smalltalk.
The second one is the imperative structure language. Programmers can directly derive it from the C language which uses descriptions that change a program’s state. It basically expresses commands for the computer to perform and focuses on how the programs work. Famous examples of this are Ada, C++, Java, C#, and Phyton.
The third one is the functional programming language which defines a program and a set of instructions as a mathematical function. It is designed to manage the symbolic computations and list processing applications. It supports a bug-free code, lazy evaluation, and efficiency. Thus, this language is sub-divided into two which are pure and impure. Famous pure functional language includes Haskell, Agda, and Elm. Likewise, the famous impure functional language includes LISP.
The development of different language approaches happened in the past few years to understand generic programming easily. Definitely, these approaches are similar but have corresponding differences in regards to their specific application to build useful programs in the future. There will be tons of interactive visualization and coding challenges before fully understanding what generic programming is, but it will be all worth it in making the program faster and efficient.
