#include<cstdlib>
using namespace std;
int main()
{
string Word1,Word2,Word3,Word4,Word5;
cout<<"enter you subjects.\n";
cin>>Word1;
cin>>Word2;
cin>>Word3;
cin>>Word4;

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
int main(void) {
srand(time(NULL));
std::string Words[3];
std::cout<<"enter you subjects.\n";
std::cout << "Word 1: ";
std::cin>>Words[0];
std::cout << "Word 2: ";
std::cin>>Words[1];
std::cout << "Word 3: ";
std::cin>>Words[2];
std::cout << Words[rand() % 3] << std::endl;
return 0;
}

That should work perfectly. Just randomly generate a number (0 - 3) for the index of the Words array.
