Why are constants important in programming?
Constants are crucial because they provide meaningful names for fixed values, improve code readability, and prevent accidental changes.
Can you give an example of using constants in a program?
Sure! For instance, instead of using the number 3.14 directly, you can define a constant like const PI = 3.14;
and use PI
throughout your code.
What happens if I don't use constants?
Without constants, your code can become harder to read and maintain. Magic numbers can lead to errors and make debugging difficult.
Are there any performance benefits to using constants?
Yes, using constants can lead to performance optimizations by allowing compilers to make better decisions during code execution.
