Overloading Operators C++
Not what you're looking for?
Complete and test this exercise. Implement the default constructor and the constructor with one int parameter. Overload the + and - operators to add and subtract percents. Also, overload the * operator to allow multiplication of a percent by an integer.
Write a program to test all the member functions and overloaded operators in your class definition.
#include <iostream>
using namespace std;
class Percent
{
public:
friend bool operator ==(const Percent& first, const Percent& second);
friend bool operator <(const Percent& first, const Percent& second);
Percent();
Percent(int percent_value);
friend istream& operator >>(istream& ins, Percent& the_object);
// Overloads the >> operator to input values of type
// Percent.
// Precondition: If ins is a file input stream, then ins
// has already been connected to a file.
friend ostream& operator <<(ostream& outs, const Percent& a_percent);
// Precondition: If ins is a file input stream, then ins
// has already been connected to a file.
friend ostream& operator <<(ostream& outs, const Percent& a_percent);
// Overloads the << operator for output values of type
// Percent.
// Precondition: If outs is a file output stream, then
// outs has already been connected to a file.
private:
int value;
};
// Uses iostream:
istream& operator >>(istream& ins, Percent& the_object)
{
char percent_sign;
ins >> the_object.value;
ins >> percent_sign; // Discards the % sign.
return ins;
}
// Uses iostream:
ostream& operator <<(ostream& outs, const Percent& a_percent)
{
outs << a_percent.value << '%';
return outs;
}
