All Operators

All Operators

A compact scan page listing the main C and C++ operators, punctuators, and alternative operator tokens.

How to use this reference page

Use reference pages to confirm names, categories, nearby facilities, and the constraints that matter before writing or reviewing code.

Scan the top of the page first to identify the primary types, functions, or algorithm families involved.
Use the nearby-page links when your question is really about a companion header, related algorithm family, or broader subsystem.
Validate tricky behavior with a small compileable example before relying on memory for details like invalidation, ordering, allocation, or lifetime rules.

All Operators

This page is optimized for fast scanning. Use Operators and punctuators when you want the grouped explanations and caveats.

Arithmetic

+, -, *, /, %
unary +, unary -
++, --

Comparison

==, !=, <, <=, >, >=
<=>

Logical

!, &&, ||
alternative tokens: not, and, or

Bitwise and shifts

~, &, |, ^, <<, >>
compound forms: &=, |=, ^=, <<=, >>=
alternative tokens: bitand, bitor, xor, compl, and_eq, or_eq, xor_eq

Assignment and conditional

=
+=, -=, *=, /=, %=
?:

Access and calls

., ->, [], ()
::, .*, ->*

unary &, unary *
C cast syntax: (type)
static_cast, dynamic_cast, const_cast, reinterpret_cast
sizeof, alignof, decltype, typeid, noexcept

Punctuation and separators

,, ;, :
{ }, ( ), [ ], < >
...

Practical use

Use this page when you need to scan quickly.
Use Operators and punctuators when you need context or overloadability notes.

Example in practice

#include <iostream>

struct Point {
    int x{};
    int y{};
};

int main() {
    Point p{3, 4};
    int total = (p.x + p.y) * 2;
    bool large = total >= 10 && p.x != 0;
    std::cout << (large ? total : 0) << '\n';
}
