算术运算符 (Arithmetic Operators)

Arithmetic operators are the special symbols that are used for the Arithmetic / Mathematical operations. These operators can be unary and binary.

算术运算符是用于算术/数学运算的特殊符号。 这些运算符可以是一元和二进制。

Following are the types of Arithmetic Operators,

以下是算术运算符的类型 ，

• Arithmetic unary operators

  一元算术运算符

• Arithmetic binary operators

  算术二进制运算符

一元算术运算符 (Arithmetic unary operators)

For the unary operations – we need only one operand. These are the operators,

对于一元运算，我们只需要一个操作数。 这些是操作员，

1. Unary plus (+)

   一元加(+)

2. Unary minus (-)

   一元减(-)

Syntax:

句法：

+a
-a

Example:

例：

Input:
int a = -10;
    
Operation & Output:
+a = -10
-a = 10

C++ program to demonstrate the example of arithmetic unary operators

C ++程序演示算术一元运算符的示例

#include 
using namespace std;

int main()
{
    int a = 10;
    int b = -10;

    // printing the values
    cout << "a: " << a << endl;
    cout << "b: " << b << endl;

    // unary plus operations
    cout << "+a: " << +a << endl;
    cout << "+b: " << +b << endl;

    // unary minus operations
    cout << "-a: " << -a << endl;
    cout << "-b: " << -b << endl;

    return 0;
}

Output:

输出：

a: 10
b: -10
+a: 10
+b: -10
-a: -10
-b: 10

算术二进制运算符 (Arithmetic binary operators)

For the binary operations – we need two operands. These are the operators,

对于二进制运算–我们需要两个操作数。 这些是操作员，

Operator	Name	Description
+	Plus operator	Returns the addition of two operands.
-	Minus operator	Returns the subtraction of two operands.
*	Multiplication operator	Returns the multiplication (product) of two operands.
/	Divide operator	Returns the result of the division of two operands i.e. returns the quotient of the division operation.
%	Modulus operator	Returns the remainder of the division operation on two operands.

操作员	名称	描述
+	加号运算符	返回两个操作数的加法。
--	减号	返回两个操作数的减法。
*	乘法运算符	返回两个操作数的乘积(乘积)。
/	除法运算符	返回两个操作数的除法结果，即返回除法运算的商。
％	模算子	返回两个操作数上除法运算的其余部分。

Syntax:

句法：

a + b
a - b
a * b
a / b
a % b

Example:

例：

Input:
int a = 10;
int b = 3;
    
Operation & Output:
a + b = 13
a - b = 7
a * b = 30
a / b = 3
a % b = 1

C++ program to demonstrate the example of arithmetic binary operators

C ++程序演示算术二进制运算符的示例

#include 
#include  // for fmod() func.
using namespace std;

int main()
{
    int a = 10;
    int b = 3;

    // printing the values
    cout << "a : " << a << endl;
    cout << "b : " << b << endl;

    // arithmetic operations
    cout << "a + b : " << a + b << endl;
    cout << "a - b : " << a - b << endl;
    cout << "a * b : " << a * b << endl;
    cout << "a / b : " << a / b << endl;
    cout << "a % b : " << a % b << endl;
    cout << endl;

    float x = 10.23f;
    float y = 3.10f;

    // printing the values
    cout << "x : " << x << endl;
    cout << "y : " << y << endl;

    // arithmetic operations
    cout << "x + y : " << x + y << endl;
    cout << "x - y : " << x - y << endl;
    cout << "x * y : " << x * y << endl;
    cout << "x / y : " << x / y << endl;
    // % operator doesn't work with float values
    // use fmod() for this
    // cout << "x % y : " << x % y << endl;
    cout << "fmod(" << x << " , " << y << ") : " << fmod(x, y) << endl;

    return 0;
}

Output:

输出：

a : 10
b : 3
a + b : 13
a - b : 7
a * b : 30
a / b : 3
a % b : 1

x : 10.23
y : 3.1
x + y : 13.33
x - y : 7.13
x * y : 31.713
x / y : 3.3
fmod(10.23 , 3.1) : 0.93
