    copied!<p>My issue is I am trying my first attempt at writing a very basic lexical analyzer for ascii text files. so far, it reads and compares to my token list properly, however I am unable to grab the final token without a space or pressing enter. I've tried using the delimiter ^Z ASCII 26 as another selection before comparing the string to my token list. This failed to work. I've also tried moving the f->eof() check to below the comparison location to see if it will snag it then check the eof flag. I've had no luck. could anyone possibly enlighten me? The code is below for the read method. m_TokenList is just a vector of type string.</p> <pre><code>void CelestialAnalyzer::ReadInTokens(ifstream *f){ vector&lt;string&gt; statement; vector&lt;string&gt; tokens; string token; char c; do{ f-&gt;get(c); // Read in each character if(f-&gt;eof()) break; if(c == '\n' || c == ' ' || c == '^Z' || c == '\r'){ // 26 ASCII ^Z (end of file marker) for(unsigned int i=0; i&lt;m_TokenList.size(); i++){ if(!token.compare(m_TokenList[i])){ tokens.push_back(token); token.clear(); } } } else { token.push_back(c); // Add it to the token array } } while (true); f-&gt;close(); for(unsigned int i=0; i&lt;tokens.size(); i++){ cout &lt;&lt; "Found Token: " &lt;&lt; tokens[i].c_str() &lt;&lt; endl; } </code></pre> <p>}</p> <p>The m_TokenList is initialized as</p> <pre><code>CelestialAnalyzer::CelestialAnalyzer(){ m_TokenList.push_back("KEY"); // Prints data m_TokenList.push_back("GETINPUT"); // Grabs user data m_TokenList.push_back("+"); // Addition/Concation m_TokenList.push_back("-"); // Subtraction m_TokenList.push_back("=="); // Equator m_TokenList.push_back("="); // Assignment m_TokenList.push_back(";"); // End statement m_TokenList.push_back(" "); // Blank m_TokenList.push_back("{"); // Open Grouping m_TokenList.push_back("}"); // Close Grouping m_TokenList.push_back("("); // Parameter opening m_TokenList.push_back(")"); // Parameter closing for(unsigned int i=48; i&lt;=57; i++){ string s; s.push_back((char)i); m_TokenList.push_back(s); s.clear(); } } </code></pre> <p>A test file for reading is this simple example. 1 + 2 = KEY</p> <p>It will register all but 'KEY' unless there is a space or a newline after it.</p>
