IV. Programming

Basic Principles of Programming

• Algorithms: An algorithm is a step-by-step procedure or formula for solving a problem. Programming involves writing algorithms to execute specific tasks.

• Control Structures: These include decisions (if statements), loops (for, while), and branching, which control the flow of a program.

• Data Structures: Efficient handling of data types and structures (like arrays, lists, stacks, and queues) is crucial for effective problem-solving.

• Syntax and Semantics: Each programming language has its own set of rules (syntax) and meanings (semantics) that define the structure and operation of the program.

• Testing and Debugging: Programmers must regularly test their code for errors and debug when necessary to ensure the program works as intended.
