Study Notes
Problem Solving Basics
- Computers solve problems through programmed solutions.
- Problem-solving steps include:
- Defining the problem
- Creating an algorithm
- Writing the program code
- Testing and debugging the program
What is Programming?
- Programming solves problems by writing computer code.
- Programs perform algorithm steps.
Algorithm Definition
- An algorithm provides step-by-step instructions to solve a problem.
- Algorithms are used as a foundation for creating computer programs.
- Algorithms can be visually presented as a flowchart.
Algorithm Design Constructs
- Sequencing: Instructions executed one after another.
- Selection: Decision or question leads to one of two program actions, often using IF statements.
- Iteration: Repetition of a sequence of instructions using loops until a condition is met.
- Includes constructs such as "repeat block", "repeat until block", and "forever block".
Flow Chart Basics
- A flowchart is a visual representation of an algorithm.
- Flowcharts use standard shapes connected by arrows.
- Each shape represents a step in the algorithm.
Flow Chart Shapes
- Start/End Shape: Indicates the start and end points of the flowchart.
- Input/Output Shape: Represents input or reading data and output or printing data.
- Process Shape: Shows a processing operation.
- Decision Shape: Represents a decision-making point with two or more alternatives.
- Arrows: Connect the shapes and indicate the direction of the chart.
Debugging
- A bug is a mistake or error in an algorithm or computer program.
- A bug causes computer programs not to work as expected.
- Debugging identifies and fixes errors or bugs in a program.
