  1. Declare Variables:

  2. Explanation: In this step, we declare the variables that will be used in the program. Variables are used to store data of different types, such as integers, floating-point numbers, characters, etc.

  3. Input:

  4. Explanation: The input step involves obtaining data from the user or from another source and storing it in the previously declared variables. This data will be used in subsequent steps of the program.

  5. Processing:

  6. Explanation: In the processing step, the program performs calculations or manipulates the input data in some way. This can involve arithmetic operations, logical operations, conditional statements, loops, and other programming constructs.

  7. Output:

  8. Explanation: The output step involves displaying the results of the processing step to the user or to another system. This can be done through the console, a graphical user interface, a file, or another output medium.

  9. Error Handling:

  10. Explanation: Error handling is the process of dealing with unexpected or erroneous input or conditions within the program. This can involve validation of input, exception handling, and other techniques to ensure the program behaves as expected even in the presence of errors.
