Question

How to write constructor outside a class definition in C++

Answer 1

#include <iostream>

using std::cout;
using std::endl;

class Base {
	int a, b, c;
public:
	Base(int _a, int _b, int _c);

	void print() {
		cout << a << " " << b << " " << c << endl;;
	}
};

Base::Base(int _a, int _b, int _c) {
	a = _a;
	b = _b;
	c = _c;
}

int main()
{
	Base o(3, 22, 878);

	o.print();

	return 0;
}

/*
run:

3 22 878

*/
