Key Concepts

Conditional Statement

A conditional statement is a programming construct that executes a block of code only if a specified condition evaluates to true. It is fundamental to controlling the flow of a program and enables decision-making based on different criteria.

Boolean Logic

Boolean logic involves using truth values—true and false—to evaluate expressions. It employs logical operators such as AND, OR, and XOR to combine multiple conditions, which is essential in forming complex conditional expressions in programming.

Arithmetic Expression Evaluation

Arithmetic expression evaluation refers to the process of computing numerical expressions involving variables and constants. These expressions are often used within conditions to check if certain numerical relationships hold true, influencing program behavior.

Relational Operators

Relational operators compare two values or expressions and return a boolean result. They are used in conditional statements to determine the relationship (such as equality or inequality) between operands, thereby directing program execution.

Assignment Operation

An assignment operation updates the value stored in a variable. In programming, it typically takes the form of assigning a new value, computed from an expression, to a variable, thereby altering the program's state.
