Hard code is a term used in computer programming to describe a portion of program that cannot be changed without modifying the source code itself. Once the software is compiled and converted into an executable file, the hardcoded part of the program remains constant regardless of any modifications done to the software.
Why Do We Use Hard Code?
Hardcoding is usually done for fixed values and parameters that should remain constant such as pi or the speed of light. These are basic constants used in sciences like physics and chemistry or mathematics in general. Hardcoding ensures that the value remains the same during the runtime of a program and cannot be changed by the user or any other external source.
Some developers consider hardcoding a bad programming practice, but it also has its merits. For example, unique serial numbers are sometimes hardcoded in software to ensure the validity of the copy.
Is Hardcoding Used in Programming Languages?
Hard code is a term used to describe a programming language that is more difficult than other languages. A written code that is unlikely to change is also considered hard coded, for example, code written to ROM.
FAQs
What is the meaning of hardcoding in programming?
Hardcoding refers to a portion of code that cannot be altered except by modifying the source code of the program itself.
Why do programmers use hard code?
Programmers use hard code to keep fixed values and parameters that should remain constant and unchanged during the runtime of the program.
What are the benefits of hard coding?
Hard coding can be useful in situations where constant values or parameters need to stay fixed, for example, unique serial numbers hardcoded in software to ensure the validity of the copy.
Conclusion
Hard code is a programming term that refers to code that cannot be changed once a program is compiled and turned into an executable file. It is useful for constants and parameters that should remain unchanged during the runtime of the program. While some developers consider hardcoding a bad programming practice, it can also be useful in certain situations like ensuring the validity of a software copy.
