Thread: substrings and loops, messing up real bad!

Code:

#include <iostream>
using namespace std;

int main ()
    {
    string wd[50];
    cout<<"Trivia will begin"<<"\n"<<"\n";
    wd[1] = "hello";
    wd[2] = "need";
    wd[3] = "help";
    wd[4] = "yell";
    wd[5] = "box";
    string subs[50];
    int low_index = 1;
    int high_index = 5;
    int lsub_index = low_index;
    int hsub_index = high_index;
    bool subs_has_set[50];
    int players_points;
    for (int t = 0; t < 51; t++)
        {
        subs_has_set[t] = false;
        }
    int x; int i;
    bool cont = true;
    string players_word;
    string scrambledword;
    //makes a random number, to select the word we will use
    srand((unsigned)time(0));   
    x = 1; //(rand()%high_index)+low_index;
    //gets the length of the string for the while loop
    string::size_type word_length = wd[x].length();
    
    cout<<"0,1 = "<<wd[x].substr(0,1)<<"\n";
    //begins to set subs[] to each letter of wd
    cout<<"wd[x] == "<<wd[x]<<","<<"\n"<<"Length = "<<word_length<<"\n"<<"\n";
    while (low_index-1 < word_length)
        {
        subs[low_index] = wd[x].substr(low_index-1, low_index);
        cout<<"subs["<<low_index<<"] == "<<subs[low_index]<<"\n"<<"\n";
        low_index++;
        }
    //loops so all characters are used and not overlap
    while (cont == true)
        {
        i = (rand()%word_length)+1;
        if (subs_has_set[i] == false)
            {
            scrambledword = scrambledword + subs[i]; 
            subs_has_set[i] == true;   
            cout<<"subs[i], "<<subs[i];       
            }
        string::size_type new_word_length = scrambledword.length();
        if (new_word_length == word_length)
            {
            cont == false; 
            } 
        cin.get();
        }
    cout<<"Word to unscramble is "<<scrambledword<<", Good luck "<<"\n";
    getline(cin, players_word);
    if (players_word == wd[x])
        {
        players_points = players_points + 1;
        cout<<"Correct, +1 Point";
        }
    cin.get();
    }

the red part, is suppost to loop through each letter of the word, and add it to subs[low_index]but when I display it, it ends up

- updated with latest code

please help!


I did this

subs[low_index] = wd[x].substr(low_index-1, low_index);

and got

subs [1] = h
subs [2] = el
subs [3] = llo
subs [4] = lo
subs [5] = o

which is closer
