Introduction to Arithmetic Operators in C++

Arithmetic operators are used to performing some mathematical operations. Like any other operator, C++ also supports arithmetic operators to perform some mathematical actions like addition, subtraction, multiplication, etc. In this article, we are going to discuss those operators supported by the C++ language.

Top 7 Arithmetic Operators in C++

Below is the list of different operators explained in more detail.

  1. Addition Operator (+): It is used to add two operands. Suppose X and Y are two operands, this plus operators will add up these two operands X + Y.
  2. Subtraction Operator (-): It is used to subtract two operands. Suppose X and Y are two operands, then this minis operator will subtract the value of the second operand from the first operand.
  3. Multiplication Operator (*): It is used to multiply two operands. Suppose X and Y are two operands then this multiplication operator will multiply X with Y.
  4. Division Operator (/): It is used to numerator by the denominator. Suppose X and Y are two operands, this division operator divides the numerator by denominator.
  5. Modulus Operator (%): It is used to give the remainder of the division. Suppose X and Y are two operands then this modulus operator first divides the numerator by denominator and gives the remainder.
  6. Increment Operator (++): It is used to increment the value of the variable by 1. Suppose X is the operand, then this increment operator will add the value of X by 1.
  7. Decrement Operator (–): It is used to decrementing the value of the variable by 1. Suppose X is the operand, this decrement operator will decrement the value of X by 1.

Examples of Arithmetic Operators in C++

Let’s discuss some examples to understand them in a better way.

Example #1 – Program to Use Addition (+) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X, Y, total; cout << "Enter the value of X: "; cin >> X; cout << "Enter the value of Y: "; cin >> Y; total = X + Y; cout << "Addition of X and Y is: " << total; return 0; }

Output:

Example #2 – Program to Use Subtraction (-) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X, Y, subtract; cout << "Enter the value of X: "; cin >> X; cout << "Enter the value of Y: "; cin >> Y; subtract = X - Y; cout << "Subtraction of Y from X is: " << subtract; return 0; }

Output:

Example #3 – Program to Use Multiplication (*) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X, Y, multiply; cout << "Enter the value of X: "; cin >> X; cout << "Enter the value of Y: "; cin >> Y; multiply = X * Y; cout << "Multiplication of X and Y is: " << multiply; return 0; }

Output:

Example #4 – Program to Use Division (/) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X, Y, divide; cout << "Enter the value of X: "; cin >> X; cout << "Enter the value of Y: "; cin >> Y; divide = X/Y; cout << "Division of X and Y is: " << divide; return 0; }

Output:

Example #5 – Program to Use Modulus (%) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X, Y, remainder; cout << "Enter the value of X: "; cin >> X; cout << "Enter the value of Y: "; cin >> Y; remainder = X % Y; cout << "Remainder of X and Y is: " << remainder; return 0; }

Output:

Example #6 – Program to Use Increment (++) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X; cout << "Enter the value of X: "; cin >> X; X++; cout << "Incremented value of X: " << X; return 0; }

Output:

Example #7 – Program to Use Decrement (–) Arithmetic Operator

Code:

#include <iostream> using namespace std; int main() { int X; cout << "Enter the value of X: "; cin >> X; X--; cout << "Decremented value of X: " << X; return 0; }
