Answer 1

#include<iostream>
using namespace std;
class  String1{
	private:
	string	str1;
		public:
		void setS1(string d){
			str1 = d;
		}
		
		string getS1(){
			return str1;
		}
	
};


class  String2{
	private:
		string	str2;
	public:
		void setS2(string d){
			str2 = d;
		}
		
		string getS2(){
			return str2;
		}
};


class StringConcat:String1, String2 {
	private:
		
		string s3;
	public:
		
		StringConcat(string s, string a){
			setS1(s);
			setS2(a);
			s3 = getS1() +" "+getS2();
		}
		
		void display(){
			cout<<s3<<endl;
		}
		
}; 


int main(){
	StringConcat s("John", "Paul");
	s.display();
}
