constructor in derived class in c++ code example
Example 1: c++ base constructor
class Derived: public Base
{
public:
double m_cost;
Derived(double cost=0.0, int id=0)
: Base{ id },
m_cost{ cost }
{
}
double getCost() const { return m_cost; }
};
Example 2: constructor derived class c++
#include <iostream>
using namespace std;
class Complex
{
int a, b;
public:
Complex(int x, int y)
{
a = x;
b = y;
}
Complex(int x)
{
a = x;
b = 0;
}
Complex()
{
a = 0;
b = 0;
}
void printNumber()
{
cout << "Your number is " << a << " + " << b << "i" << endl;
}
};
int main()
{
Complex c1(4, 6), c2(4), c3;
c1.printNumber();
c2.printNumber();
c3.printNumber();
return 0;
}
