Study Notes
Algorithms
- An algorithm is a structured, step-by-step process for solving a problem.
- It's like a recipe with clear instructions to achieve a desired outcome.
- Algorithms must be finite, meaning they have a defined ending point.
- Pseudocode is a way to represent algorithms using human-readable language (English)
Computer Programming
- Programmers write sets of instructions called programs, to tell computers what to do.
- Machine language, consisting of 1s and 0s, is the lowest level of programming language.
- Mnemonic code uses letters to represent instructions, making programming more readable.
- High-level programming languages are closer to human language and need interpreters or compilers to translate code into machine language.
Computer Fundamentals
- Electricity powers computers, enabling them to function.
- Input streams are sequences of characters flowing from an input device (like a keyboard) to the computer.
- Output streams are sequences of characters sent from the computer to an output device (like a monitor).
Flowcharts
- Flowcharts are visual representations of algorithms that show the order of steps.
- They use symbols to illustrate different operations and the flow of data.
- Common symbols include start/stop, input/output, process, and decision making.
Flowchart Structures
- Sequence Structure: Steps in a flowchart are executed in a linear order, one after another.
- Selection Structure (Conditionals): The flowchart branches based on whether a condition is true or false.
- Repetition Structure (Loops): Steps are repeated until a specific condition is met.
C++ Programming
- In C++, all variables need unique identifier names.
