Arithmetic Operators: C++ supports these arithmetic operator.

``````Operator                Symbol              Form

Subtraction               -                 x-y
Multiplication            *                 x*y
Division                  /                 x/y
Modulus                   %                 x%y
``````

``````int x=2+3;
cout<<x;
``````

Output:

``````5
``````

Subtraction: The subtraction operator subtracts one operands from the other.

``````int x=5-3;
cout<<x;
``````

Output:

``````2
``````

Multiplication: The multiplication operator multiplies its operands.

``````int x=3*2;
cout<<x;
``````

Output:

``````6
``````

Division: The division operator divides the first operand by the second. Any remainder is dropped in order to return an integer value.

``````int x=10/3;
cout<<x;
``````

Output:

``````3
``````

If one or both of the operands are floating point values,the division operator performs floating point division.

Modulus: The modulus operator (%) is informally know as the remainder operator because it returns the remainder after an integer division.

``````int x=25%6;
cout<<x;
``````

Output:

``````1
``````

Operator Precedence: Operator precedence determines the grouping of terms in an expression,which affects how an expression is evaluated certain operators take higher precedence over others; for example, the multiplication operator has higher precedence over the addition operator.

For example:

``````int x=5+2*2;
cout<<x;
``````

Output:

``````9
``````

The program evaluates 2*2 first, and then adds the result 5.
As in mathematics,using parentheses alters operator precedence.

``````int x=(5+2)*2;
cout<<x;
``````

Output:

``````14
``````
