AP® Computer Science Principles

Algorithm development is a core skill in computer science. An algorithm is essentially a method or set of instructions for solving a particular problem. It

Iteration in programming is crucial for solving repetitive tasks. It allows an algorithm to cycle through a set of instructions multiple times. Therefore, it helps

Conditionals form the backbone of decision-making in programming. They enable a program to choose different paths based on specific conditions. For example, a simple program

Conditional statements play a major role in programming because they allow programs to make decisions based on specific conditions. Therefore, these statements determine which parts

Boolean expressions are statements that can be evaluated as either true or false. They are at the heart of many decisions that computers make, such

Strings are among the most common data types found in nearly every programming language. They are essential for tasks like displaying text, handling user input,

Mathematical expressions play a major role in programming and problem-solving. They form part of the instructions that tell a computer what to do and how

Data abstraction is a powerful concept that simplifies how data is organized, stored, and managed in computer programs. It enables developers to treat data as

Variables in programming are like labeled boxes that hold information. They make it possible to store, retrieve, and update data throughout a program. Often, data
