C++ :: How To Prevent Loop Running Over

i am writing a function that takes a delimited string and splits the strings into it's respective words according to the delimeter.

1) iterate through string and store delimeter position in vector array.

2) iterate through again and use substr to split into words and store again in a vector.

I then have a dictionary file, and am comapring each values in the string with each in the dictionary, problem is that it overruns the loop and obviously gives a subscript out of range error.

Code:
#include <iostream>#include <fstream>
#include <vector>
using namespace std;
//Start with string inputString
//Find delimeters ::pos as ints and stores positions in vector <int> array
//Run though string using 'find' and seperate string by positions of char32s
//Build vector<string> array of individual words in string
//Open dictionary file and loop though testing each words in vector string array against each word in dictionary
