#include <iostream>
using namespace std;
class DB;
class DM{
	public:
		DM(){}
		DM (float meter, float cm);
		friend int func(DM,DB);
};

class DB
{
float ft;
float inches;

public:
DB(){}
DB(float fe,float inc){
ft=fe;
inches=inc;
};

void display(){

	cout<<"\n Feet is :"<<ft;
	cout<<"\nInches are:"<<inches;
};
int main (){
	DM a;
	DB b;
	cout<<"Data : "<<func(a, b);
	return 0;
}

Hello! I have some questions/observations:

1. Why did you write class DB in both lines 3 and 11?
2. In line 25, you try to directly access private variable ft. It can't be done, even if you have an object of its class - DB (which you don't). The same happens in line 26 with variable inches.
3. In which line(s) is the error, according to the compiler/linker?

You need one more '};' after finishing main(), for class DB
