Defining Member function outside the class defination using C++

By Pratyasha Sahu

This code helps us to understand how to define a member function outside the class definition in C++.

A User-defined datatype which can be declared and used in the program to create objects is called as a Class.

#include
using namespace std;
class unit
{
int number;
float cost;
public:
void getdata(int a, float b);
void putdata(void)
{
cout<<"number:"<<number<<endl;
cout<<"cost:"<<cost<<endl;
}
};
void unit::getdata(int a, float b)
{
number=a;
cost=b;
}

int main()
{
unit p;
cout<<"\nobject p"<<endl;
p.getdata(100,299.95);
p.putdata();
unit r;
cout<<"\nobject p"<<endl;
r.getdata(200,1759.95);
r.putdata();
return 0;
}
