为什么这个 function 输出一个字多次而不是一个？

Question

#include <iostream>
#include <string>//needed to make string array
#include <fstream>//Needed for redaing in from external file
#include <cstdlib>//needed for rand() function (for random word)
#include <ctime>//needed for time() funtion to seed rand()
using namespace std;

void wordPick();
int main()
{
    wordPick();

    return 0;
}

void wordPick()//reads in external file and puts it in an array for a library of words to randomly choose
{
    char secretWord;
    srand(time(0));
    ifstream inFile("randwords.txt");
    if(inFile.is_open())
    {
        string wordlist[10];
        for(int i = 0; i < 10; ++i)
        {
            inFile >> wordlist[i];
            srand(time(0));
            string secretword = wordlist[rand() % 10];
            cout<< secretword << endl;
        }
    }
}

my program is supposed to take a random word from an external file list and output it one time but instead, it is basically writing over the rest of the list with the chosen word.

This is for a game of Hangman that the user will have to guess so it needs to be only once. Can anyone help its due in 3 days.

Answer 1

Move this:

srand(time(0));
string secretword = wordlist[rand() % 10];
cout<< secretword << endl;

outside of your for loop, and remove the redundant call to srand(time(0)) :

for(int i = 0; i < 10; ++i)
{
    inFile >> wordlist[i];
}

string secretword = wordlist[rand() % 10];
cout<< secretword << endl;
