Read words from file, choose one then output

[Ch1156]

Ok so i want the program to be able to read a list of words from a file and then randomly choose one then output it all jumbled up. I already know how to jumble them up but i dont know how to input the list then randomly choose one. Heres what i got so far

#include <iostream>
#include <string>
#include <algorithm>
#include <ctime>
#include <cstdlib>
#include <fstream>
#include <sstream>

using namespace std;

void word_list()
{
    string store_list = " ";
    
    ifstream fileIn;
    fileIn.open("word list.txt");

    stringstream ss(stringstream::in | stringstream::app | stringstream::out);
}

int main()
{
    word_list();
    
    
    srand(time(0));

    string original_word = " ";
    string shuffled_word = " ";
    string guess = " ";

    bool game_loop = true;

    cout << "CRYPTO GUESS\n" << endl;

    //Main Game loop

    while(game_loop != false)
    {
        cout << "Please enter your word" << endl;
        cin >> original_word;

        shuffled_word = original_word; //#1
        random_shuffle(shuffled_word.begin(), shuffled_word.end()); //#2

        for(int i = 0; i < 300 ; i++)
        {
            cout << "\n";
        }

        cout << shuffled_word << endl;

        cout << "\n";

        while(guess != original_word)
        {
            cout << "Your guess: ";
            cin >> guess;

            if(guess == original_word)
            {
                cout << "Is correct!\n" << endl;
                break;
            }
            else if(guess == "Quit" || guess == "quit")
            {
                cout << "Goodbye thanks for playing" << endl;
                return 0;
            }
            else
            {
                cout << "Is wrong! Try again\n" << endl;
            }
        }
    }
}

does anyone know?

I may be able to help you out. I just recreated your game for fun, and you can check my source to see what I used to make it work.

So to answer your question "i dont know how to input the list then randomly choose one"...
To input the list of words I used std::ifstream (starting on line 17) to open the word list file, then copied the file data line by line into an std::vector of std::strings (starting on line 34). Then I used a Pseudo Random Number Generator I found with a quick google search (starting on line 7) to get a random number within the limits of the vector of words (line 64) to pick the word to be scrambled (line 67).

I hope I've been of help.

#include <iostream>
#include <fstream>
#include <vector>
#include <algorithm>


unsigned int RandomInt(unsigned int min, unsigned int max)
{
	return (rand() % ((max + 1) - min) + min);
}

int main()
{
	// #Step One# - Open File
	//===========================================
	std::string wordFile = "./wordList.txt";
	std::ifstream fileIn(wordFile.c_str());

	// Check if the file was opened sucessfully
	if(!fileIn)
	{
		std::cerr << "err: Failed To Load (" << wordFile << ")\n";
		return EXIT_FAILURE;
	}
	
	
	
	// #Step Two# - Read Words From File
	// (Assuming each word is on its own line.)
	//===========================================
	std::vector<std::string> words;
	std::string line;
	
	while(getline(fileIn, line))
	{
		words.push_back(line);
		line.clear();
	}
	
	fileIn.close();
	
	// Check if the words list was populated
	if(words.empty())
	{
		std::cerr << "err: No Words Found\n";
		return EXIT_FAILURE;
	}
	
	
	
	// #Step Three# - Game Loop
	//===========================================
	std::cout << "! - CRYPTO GUESS - !\n";

	// Seed the pseudo random number generator
	srand(static_cast<unsigned int>(time(NULL)));
	
	for(bool quitGame = false;  quitGame == false;)
	{
		// %Part One% - Pick A Random Word
		//-------------------------------------
		
		// Generate Random Number
		unsigned int randomNumber = RandomInt(0, words.size() - 1);
		
		// Set the word
		std::string word = words[randomNumber];
		
		
		// %Part Two% - Shuffle the Word
		//-------------------------------------
		std::string shuffledWord = word;
		std::random_shuffle(shuffledWord.begin(), shuffledWord.end());
		
		// %Part Three% - Guess The Word
		//-------------------------------------
		std::cout  << "\n[Shuffled Word]: " << shuffledWord
		           << " (Type q to Quit)\n" << "Your guess...\n";
		
		for(bool done = false; done == false;)
		{
			std::string answer;
			std::cin >> answer;
			
			if(answer == word)
			{
				std::cout << "Is Correct!\n";
				done = true;
			}
			
			else if((answer == "q") || (answer == "Q"))
			{
				done = true;
				quitGame = true;
			}
			
			else
			std::cout << "Is Incorrect...Try Again!\n";
		}				
	}	
	
	
	// #Step Four# - Exit
	//===========================================
	std::cout << "Thanks for Playing!\n";
	return EXIT_SUCCESS;
}
