Is there another simpler or shorter method to write this code? I would like to know other routes (beginner here)

I'm currently a CE major who got accepted to a tech company training program that will consist of Java and C++. I concentrated on Network Security and Embedded systems. I took c++ and java, but they were introductory courses, and it was during my first two years of college. I am practicing my coding skills by writing foolish codes that entertain me. I wanted to know if there are other methods to write the code I wrote below.

#include <iostream>
#include <string>
using namespace std;

int main() {
    string a, b, c, e;
    double d;
    string x[] = { "Yes","yes","No","no","Modern","Warfare","modern","warfare" };
    cout << "Hello user, What is your first name?" << "\n";
    cin >> a;
    cout << "Thank you," << " " << a << "! Can I ask you a question? Yes or No?" << "\n";
    cin >> b;
    if (b == x[0] || b == x[1]) {
        cout << "Which game do you like between Modern Warfare and Cold  War?" << "\n";
        cin >> c >> e;
        if (c == x[4] && e == x[5] || c == x[6] && e == x[7]) {
            cout << "What is your kd?" << "\n";
            cin >> d;
            if (d <= 1) { 
                cout << "You're dog water. Uninstall." << "\n";
            }
            else if (1 < d && d < 2) { 
                cout << "You're alright in the game, keep practicing." << "\n";
            }
            else if (2 < d && d < 3) { 
                cout << "you can play with us!" << "\n";
            }
            else {
                cout << "Go stream on Twitch, you're a goat!";
            }
        }
        else {   
            cout << "We dont play that game, sorry." << "\n";
        }
    }
    else {
        cout << "Thank you for participating, have a great day!";
    }
}
