Computer Science I: Getting Started

These flashcards cover fundamental concepts, definitions, and programming practices introduced in the Computer Science I lecture.

Data Types

Classifications of data that tell the compiler or interpreter how the programmer intends to use the data.

Variables

Named storage locations in memory that can hold different values during the execution of a program.

Arithmetic Operations

Mathematical calculations performed using operators such as addition, subtraction, multiplication, and division.

Compiler

A program that translates source code written in a high-level language into machine code.

Interpreter

A program that executes instructions written in a programming or scripting language without requiring them to have been compiled into machine language.

Algorithm

A step-by-step procedure for solving a problem or performing a task.

Source Code

The human-readable instructions and statements written in a programming language.

Machine Code

Low-level code that is directly executed by the computer's CPU.

High-Level Language (HLL)

A programming language that is more abstract than assembly or machine code, making it easier for humans to read and write.

printf

A standard library function in C used to output formatted text to the console.

Variable Declaration

The process of defining a variable's type and name before using it in a program.

Function Header

The line in a function that specifies the function's name, return type, and parameters.

Identifier

A name given to a variable, function, or other user-defined item in a program.

Keyword

Reserved words in a programming language that have special meaning and cannot be used as identifiers.

Common Programming Errors

Frequent mistakes made by programmers such as syntax errors and logical errors.

Arithmetic Operation Example

Calculating the sum of numbers using n(a+b)/2 formula.
