模板

无须修改 wdSize，程序会自动计算。

#include <bits/stdc++.h>
#include <windows.h>
#include <conio.h>
using namespace std;

int wdSize;
string world[] = {
    // 用下面的模板替换 
};

int randInt(int l, int r)
{
	static random_device rd;
	static mt19937 gen(rd());
    uniform_int_distribution<int> dist(l, r);
    return dist(gen);
}

void game()
{
	int n = randInt(0, wdSize - 1);
	
	if (n > 0)cout << world[n - 1] << "\n";
	for (int i = 0; i < world[n].size(); ++i)cout << "_";
	cout << "\n";
	if (n < wdSize - 1)cout << world[n + 1] << "\n";
	
	string input;
	cin >> input;
	if (input == world[n])
	{
		cout << "True\n";
		Sleep(2000);
	}
	else
	{
		cout << "False, the answer is\n\n" << world[n];
		cout << "\n\n按任意键继续...";
		_getch();  // 等待用户按任意键
	}

	system("cls");
}

int main()
{
	wdSize = sizeof(world) / sizeof(world[0]);
	while (1)
	{
		game();
	}
	return 0;
}
