Beginner Topic 3 of 54 Programming Fundamentals

Operators

Symbols that perform arithmetic, comparison or logical computation on operands.

How it works

Operators combine operands: arithmetic (+ - * / %), comparison (== < >), logical (and or not) and bitwise (& | ^ << >>). Precedence decides evaluation order; parentheses override it.

Where it is used

Used in every expression, from computing averages to testing x % 2 == 0 for evenness.

Common pitfall

Confusing = (assign) with == (compare), and integer division surprises such as 7 / 2 giving 3 in some languages.

Where it fits in the course

Operators is topic 3 of 54 in Programming Fundamentals, rated Beginner. It follows Data Types. The next topic is Expressions.
