Define Constant in programming. 2. Write how Constants Can be used in programming

Here are the answers to your questions: 1. Define Constant in programming A constant in programming is a named storage location that holds a value which cannot be changed during the execution of a program. Once a constant is assigned a value, it remains fixed throughout the program's runtime. 2. Write how Constants can be used in programming Constants are used in programming for several reasons: Readability: They make code easier to understand by giving meaningful names to fixed values (e.g., PI for 3.14159). Maintainability: If a constant value needs to be updated, it only needs to be changed in one place (its definition), rather than searching and replacing every instance in the code. Preventing Errors: By making a value constant, the compiler can prevent accidental modifications to that value later in the program, reducing bugs. Performance: In some languages, constants can allow for compiler optimizations, as their values are known at compile time. That's 2 down. 3 left today — send the next one.
