Accessing char in a vector of strings by it's iterator

Vote count:

Here's a part of my code:

std::vector<std::string> syntax_words;
//...
//Currently the above vector contains few strings
std::vector<std::string>::iterator sy_iterator = syntax_words.begin(); 

while (sy_iterator != syntax_words.end(){
    if (*sy_iterator[4] == 'X'){
//...

Basically I want to access the fifth char in the current string. Unfortunately the above code is throwing an error during compilation:

error: no match for ‘operator*’ (operand type is ‘std::basic_string<char>’)
      if (*sy_iterator[4] == 'X'){

I've also tried this:

if (sy_iterator[4] == 'X'){

But it's also throwing an error:

error: no match for ‘operator==’ (operand types are ‘std::basic_string<char>’ and ‘char’)
      if (sy_iterator[sit] == 'X'){

What should I do to make it work?
