• What is the importance of declaring and using variables and constants in programming?

  Declaring and using variables and constants allows programmers to store and manipulate data in their programs. Variables hold values that can change during execution, while constants hold values that remain fixed. By using variables and constants, programmers can create dynamic and flexible programs that can adapt to different situations.

• How are arithmetic operations applied in programming?

  Arithmetic operations, such as addition, subtraction, multiplication, and division, are used in programming for mathematical calculations. These operations can be applied to variables and constants to perform calculations and manipulate numeric data. By applying arithmetic operations, programmers can create complex algorithms and solve mathematical problems.

• What are the advantages of modularization in programming?

  Modularization in programming brings several benefits. Breaking down a program into smaller modules enhances code reusability, as modules can be reused in different programs. It also improves code maintainability and readability, as modules are smaller and easier to understand. Modularization enables parallel development, allowing multiple programmers to work simultaneously on different modules. Additionally, debugging and testing become more manageable as modules can be tested individually.

• How do you modularize a program in programming?

  Modularizing a program involves dividing it into separate modules.
  
  These modules represent specific functionalities within the program.
  
  Each module has its own defined inputs, outputs, and operations.
  
  Modules can be independent and can communicate with each other through parameters and return values.
  
  By breaking down a program into modules, it becomes more organized, modular, and easier to develop and maintain.

• What are the features of good program design in programming?

  Good program design has certain characteristics that contribute to its effectiveness and quality. These include modularity, which promotes code reuse and maintainability. Simplicity, which makes the code easier to understand and debug. Efficiency, which ensures optimal performance and minimal resource usage. Flexibility, which allows the program to adapt to changing requirements. Readability, which makes the code easy to comprehend and modify. Robustness, which ensures the program can handle unexpected inputs gracefully. Good program design also follows coding standards and best practices to ensure consistency and quality.

• What are variables and constants in a program?

  Variables and constants are named memory locations in a program that hold varying contents.

• What are literal constants in a program?

  Literal constants are fixed values, either numeric or strings, that are used directly in the program.
