C++ Arithmetic Operators

In this tutorial, we will learn about different Arithmetic Operators available in C++ programming language and go through each of these Arithmetic Operators in detail, with the help of examples.

C++ Arithmetic Operators

Arithmetic Operators are used to perform common mathematical operations like addition, subtraction, multiplication, division, etc.

Arithmetic Operators

The following table specifies symbol, example, and description for each of the Arithmetic Operator in C++.

Arithmetic Operation	Operator Symbol	Example	Description
Addition	+	a + b	Returns sum of a and b.
Subtraction	–	a – b	Returns difference of b from a.
Multiplication	*	a * b	Returns product of a and b.
Division	/	a / b	Returns the quotient when a is divided by b.
Modular Division	%	a % b	Returns reminder when a is divided by b.
Increment	++	a++ or ++a	Increments the value of a by one.
Decrement	—	a– or –a	Decrements the value of a by one.

Examples

C++ Addition

+ operator computes the addition of the two operands and returns the result.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 12;
   int b = 7;

   int sum = a + b;

   cout << "Addition : " << sum << endl;
}

Output

Addition : 19
Program ended with exit code: 0

C++ Subtraction

- operator computes the difference of right operand from left operand and returns the result.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 12;
   int b = 7;

   int diff = a - b;

   cout << "Subtraction : " << diff << endl;
}

Output

Subtraction : 5
Program ended with exit code: 0

C++ Multiplication

* operator computes the product of two operands and returns the result.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 12;
   int b = 7;

   int product = a * b;

   cout << "Multiplication : " << product << endl;
}

Output

Multiplication : 84
Program ended with exit code: 0

C++ Division

+ operator computes the division of first operand with second operand and returns the quotient.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 16;
   int b = 7;

   int div = a / b;

   cout << "Quotient : " << div << endl;
}

Output

Quotient : 2
Program ended with exit code: 0

C++ Modular Division

% operator computes the division of the given operands and returns the remainder.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 13;
   int b = 5;

   int modulo = a%b;

   cout << "Remainder : " << modulo << endl;
}

Output

Remainder : 3
Program ended with exit code: 0

C++ Increment

++ operator increments the value of the operand by one.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 12;
   ++a;
   cout << "Incremented value : " << a << endl;
}

Output

Incremented value : 13
Program ended with exit code: 0

C++ Decrement

++ operator decrements the value of the operand by one.

main.cpp

#include <iostream>
using namespace std;

int main() {
   int a = 12;
   --a;
   cout << "Decremented value : " << a << endl;
}

Output

Decremented value : 11
Program ended with exit code: 0
