Operator Function in C++ Programming Language with Examples

With the help of examples, we will learn about the many types of operators in C++ in this tutorial. An operator in programming is a symbol that performs operations on a value or variable.

Symbols that execute operations on variables and values are known as operators overloading. For instance, the addition operator + is used for addition, while the subtraction operator – is used for subtraction.

Arithmetic Operators in C++

To perform arithmetic operations on variables and data, arithmetic operators are used. As an example,

x + y;

The + operator is used to combine two variables, x and y. In C++, there are a variety of different arithmetic operators.

Assume variable A has a value of 12 and variable B has a value of 15.

Examples of Arithmetic Operators

#include <iostream>
using namespace std;

int main() {
    int x, y;
    x = 12;
    y = 15;

    // printing the sum of x and y
    cout << "x + y = " << (x + y) << endl;

    // printing the difference of x and y
    cout << "x - y = " << (x - y) << endl;

    // printing the product of x and y
    cout << "x * y = " << (x * y) << endl;

    // printing the division of x by y
    cout << "x / y = " << (y / x) << endl;

    // printing the modulo of x by y
    cout << "x % y = " << (y % x) << endl;

    return 0;
}

Assignment Operators in C++

Assignment operators are used to give a variable a value. The assignment operator’s left-side operand is a variable, while the assignment operator’s right-side operand is a value. Otherwise, the compiler will throw an error if the value on the right side is not the same data type as the variable on the left side(Operator Function in C++).

An Example of Assignment Operators

#include <iostream>
using namespace std;

int main() {
    int x, y;

    // 2 is assigned to x
    x = 43;

    // 7 is assigned to y
    y = 72;

    cout << "x = " << x << endl;
    cout << "y = " << y << endl;
    cout << "\nAfter x += y;" << endl;

    // assigning the sum of x and y to x
    x += y;  // x = x +y
    cout << "x = " << x << endl;

    return 0;
}

Output

Relational Operators in C++

To check the relationship between two operands, a relational operator is utilized.

An Example for Relational Operators

#include <iostream>
using namespace std;

int main() {
    int x, y;
    x = 5;
    y = 9;
    bool result;

    result = (x == y);   // false
    cout << "5 == 9 is " << result << endl;

    result = (x != y);  // true
    cout << "5 != 9 is " << result << endl;

    result = x > y;   // false
    cout << "5 > 9 is " << result << endl;

    result = x < y;   // true
    cout << "5 < 9 is " << result << endl;

    result = x >= y;  // false
    cout << "5 >= 9 is " << result << endl;

    result = x <= y;  // true
    cout << "5 <= 9 is " << result << endl;

    return 0;
}

Output

Logical Operators in C++

Logical operators are utilized to determine whether an expression is true or false. If the expression is true, it will return 1, but if it is false, it will return 0.

Bitwise Operators in C++

Bitwise operators are used in C++ to execute operations on single bits. They’re only compatible with char and int data types.

Summary

An operator function in C++ symbol that operates on a variable or value is known as an operator. Operators include arithmetic, logical, conditional, relational, bitwise, and assignment operators, among others Reference operator, and other specific sorts of operators are also available in C++.
