COMPROG 1 - BASIC OPERATORS AND PRECEDENCE

midterm reviewer on Computer Programming 1.

Operators

Specific symbols in a programming language that tell the compiler or interpreter to perform a specific mathematical, relational, or logical operation.

Arithmetic Operators

Used to perform basic mathematical operations on numerical values.

Operand

A value used on either side of an operator in an expression.

Relational Operators

Used to evaluate the relation between operands and generate a Boolean value.

Logical Operators

Return a Boolean value based on the Boolean result of given expressions.

Assignment Operators

Used to assign values to variables.

Order of Precedence

Collection of rules that determines the order in which operations are performed in an expression.

Precedence

The priority given to operators when evaluating an expression.

Parentheses

Used to group expressions and override the order of precedence in an expression.

Expression

A construct made up of variables and operators that evaluates to a single value.

Arithmetic expression

An expression that returns a numeric value and consists of arithmetic operators, operands, and assignment operators.

Integral expression

An arithmetic expression where all operands are integers and the expression returns an integer type value.

Floating-point expression

An arithmetic expression where all operands are floating-point numbers and the expression returns a floating-point type value.

Mixed expression

An expression that has operands of different data types and returns a floating-point number.

Rule 1

If the operator has the same types of operands, the operator is evaluated according to the type of the operand.

Rule 2

If the operator has both types of operands, during calculation, the integer is treated temporarily as a floating-point number, and the final result is a floating-point number.

Logical expression

An expression that returns a Boolean value when evaluated.
