Study Notes
Program
- A program consists of instructions written in a programming language.
- Functions analogously to a recipe, featuring variables (ingredients) and statements (directions).
- Must be converted into machine language for a computer to process, accomplished by a compiler or interpreter.
Computer Programming
- Encompasses writing, testing, debugging, and maintaining source code.
- Source code is written in programming languages like C, C++, Java, and Perl.
Generations of Programming Languages
- First Generation (1GL): Machine languages, the most basic level of programming.
- Second Generation (2GL): Assembly languages used for kernels and hardware drives; still considered low-level.
- Third Generation (3GL): High-level languages like C, C++, Java, Visual Basic, and JavaScript.
- Fourth Generation (4GL): High-level languages resembling human language, used in database programming; examples include Perl, Python, Ruby, SQL, and MATLAB.
- Fifth Generation (5GL): Languages with visual programming tools, such as Mercury and Prolog.
Algorithm
- Defined as a finite set of steps providing a sequence of actions to solve a problem.
- Involves a step-by-step approach to finding a solution.
Steps to Create an Algorithm
- Identify Inputs: Determine what data is needed and how to obtain it.
- Identify Outputs: Specify the desired outputs and their format.
- Identify Processes: Understand how to manipulate data to yield meaningful results.
- Break the Solution into Steps: Simplify the logic and flow of the program.
Example of an Algorithm
- Establishing telephone communication follows a clear sequence of steps from dialing to call disconnection.
Simple Algorithm Example: Adding Two Numbers
- Step 1: Start.
- Step 2: Take two numbers.
- Step 3: Add the numbers.
- Step 4: Print the result.
- Step 5: Stop.
Important Definitions
- An algorithm is a "finite set of steps, which provide a chain of action for solving a problem."
