How To Operator Overload To Divide By A Vector Template By Constant

Overloading stream insertion (<<) and extraction (>>) operators in C++

C++ is able to input and output the congenital-in data types using the stream extraction operator >> and the stream insertion operator <<. The stream insertion and stream extraction operators also can be overloaded to perform input and output for user-defined types like an object.

Here, it is important to make operator overloading office a friend of the class because it would be chosen without creating an object.

Following instance explains how extraction operator >> and insertion operator <<.

Example Lawmaking

#include <iostream> using namespace std; class Distance {    private:    int feet; // 0 to space    int inches; // 0 to 12    public:    // required constructors    Altitude() {       feet = 0;       inches = 0;    }    Distance(int f, int i) {       anxiety = f;       inches = i;    }    friend ostream &operator<<( ostream &output, const Altitude &D ) {       output << "F : " << D.feet << " I : " << D.inches;       return output;    }    friend istream &operator>>( istream &input, Distance &D ) {       input >> D.feet >> D.inches;       return input;    } }; int master() {    Distance D1(xi, 10), D2(v, xi), D3;    cout << "Enter the value of object : " << endl;    cin >> D3;    cout << "First Altitude : " << D1 << endl;    cout << "Second Distance :" << D2 << endl;    cout << "Third Distance :" << D3 << endl;    render 0; }

Output

$./a.out Enter the value of object : 70 10 First Distance : F : 11 I : 10 2nd Distance :F : 5 I : 11 Third Distance :F : seventy I : 10
