# CPP Operators

CPP Operators are used to perform operations on operands. Operands can be a variable or a constant. The operators are divided into various groups on the basis of the basic operations they perform.

Some of the basic operators are:

Arithmetic Operators:

The operators which are used to perform the arithmetical operations, are grouped together as Arithmetic operators.

 Operators Symbol Addition + Subtraction – Multiplication * Division / Modulus %

Assignment Operators:

The operators which are used to assign values to a variable, are grouped together as Assignment operators.

 Operators Symbol Equals To = Added Value += Subtracted Value -= Multiplicated Value *= Divided Value /= Modulus Value %=

Comparison Operators:

The operators which are used to compare two values, are grouped together as Comparison operators.

 Operators Symbol Equal == Not equal != Greater than > Less than < Greater than or equal to >= Less than or equal to <=

Logical Operators:

The operators which are used to perform logical operations, are grouped together as Logical operators.

 Operators Symbol AND && OR ||

Precedence and Associativity of C Operators:

The precedence and associativity of different types of operators in CPP are listed below.

 PRECEDENCE OPERATORS ASSOCIATIVITY Postfix Operators () [] -> . ++ – – Left to Right Unary Operators + – ! ~ ++ – – (type)* & sizeof Right to Left Multiplicative Operators * / % Left to Right Additive Operators + – Left to Right Shift Operators << >> Left to Right Relational Operators < <= > >= Left to Right Equality == != Left to Right Bitwise AND & Left to Right Bitwise XOR ^ Left to Right Bitwise OR | Left to Right Logical AND && Left to Right Logical OR || Left to Right Conditional Operator ?: Right to Left Assignment Operators = += -= *= /= %=>>= <<= &= ^= |= Right to Left Comma , Left to Right

Example:

#include <iostream.h> using namespace std; int main() { int sum1 = 10+20*10-90*10+700; int sum2 = (10+20)*10-(90*10)+700; cout << sum1 << endl; cout << sum2; return 0; }

Output:

10 100
