Study Notes
- The fundamentals of programming include understanding computers, programs, and the process of programming.
Defining a program
- A program is a sequence of instructions for a computer to perform a task.
- Programming is the process of writing programs.
Steps to becoming a successful programmer:
- Define the problem by thoroughly examining it.
- Outline the solution by analyzing the problem.
- Expand the outline into an algorithm, which is a step-by-step procedure.
- Test the algorithm for correctness by providing test data.
- Convert the algorithm into a program using a programming language.
- Document the program clearly.
- Run the program by instructing the computer to execute it.
- Debug the program to eliminate errors (bugs).
Programming Languages
- Examples include JavaScript, ActionScript, Ruby, Python, Java, C#, VB.NET, Objective-C, C++, C, and Assembly Language.
Prerequisites and Platforms
- The prerequisites for programming are minimal.
- Programs can be run on various platforms like Mac, Linux, and Windows.
Programming Task
- Programming involves planning and effort.
- Steps include defining and analyzing the problem and developing a logical solution using an algorithm.
Defining and Analyzing the Problem
- It is important to define what data needs to be provided (input) and what information should be produced (output).
Understanding Input and Output
- For a program calculating the total and average marks of a student in five subjects, the marks in the five subjects would need to be input.
- The marks in all five subjects, their total, and their average, should be displayed on the screen as output.
- Example INPUT: Bangla=60, English=80, Math=100, History=70
- Example Output: Average: 77.5
- Example Processing: Average = (Science + English + Math + History) / 4
Writing A First Program
- Get inputs from the user.
- Save the inputs.
- Use a math logic to process the inputs.
- Show the result/output.
- A user interface can be created to collect input from the user.
Handling Input, Processing and Output
- Variables can be assigned to the input for each subject: var a = (input for science), var b = (input for english), etc.
- Processing involves performing calculations, such as average = (a + b + c + d) / 4;.
- Output involves displaying the processed information, like "print average;".
- The program processes the input and shows the output.
