Key Concepts

Arithmetic Operations

Arithmetic operations involve the basic mathematical computations such as addition, subtraction, multiplication, and division. These operations are fundamental in calculating numerical values within expressions and must be performed according to specific rules.

Operator Precedence

Operator precedence sets the rules for the order in which operations in an expression are performed. It ensures that certain operations (like multiplication and division) are executed before others (such as addition and subtraction), unless overridden by parentheses.

Relational Operators

Relational operators are used to compare two values or expressions. They include operators like equals, greater than or equal to, and less than or equal to, and they return boolean results (true or false) based on whether the comparison holds.

Character Comparison

Character comparison involves evaluating characters based on their underlying numeric encoding (such as ASCII or Unicode values). This process allows determining the ordering between characters when relational operators are applied.

Boolean Evaluation

Boolean evaluation is the process of determining the truth value of an expression based on relational and logical operations. The result typically indicates whether a given comparison or condition is satisfied, returning either true or false.
