Thread: substring of a variable...

how do I get the substring of a variable?

im trying to make a "Trivia" game...

with scrambling words lol...

this is my code so far...

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 x; int i;
    bool cont;
    string players_word;
    string scrambledword;
    //makes a random number, to select the word we will use
    srand((unsigned)time(0));   
    x = (rand()%high_index)+low_index;
    //gets the length of the string for the while loop
    string::size_type word_length = wd[x].length();
    //begins to set subs[] to each letter of wd
    while (low_index < word_length+1)
        {
        subs[low_index] = wd[low_index];
        low_index++;
        }
    //loops so all characters are used and not overlap
    while (cont == true)
        {
        i = (rand()%word_length)+low_index;
        if (subs_has_set[i] == false)
            {
            scrambledword = scrambledword + subs[i]; 
            subs_has_set[i] == true;          
            }
        string::size_type new_word_length = scrambledword.length();
        if (new_word_length == word_length)
            {
            cont == false; 
            } 
        }
    cout<<"Word to unscramble is "<<scrambledword<<", Good luck "<<"\n";
    getline(cin, players_word);
    cin.get();
    }

all I want is to get substring of wd, so I can get each letter and set it to subs[low_index] then put it back together randomly
