  1. PO"No newline at end of file" warning, even after putting in a newline
    text
    copied!<p>I've been trying to learn C++ lately, and all has been going well until today. I'm trying to make a very simple application that basically just asks a user for a number and then displays the factorial of that number.</p> <p>When I try to compile the file in Cygwin (g++ factorial.cpp -o fact), I get the following warning "warning: no newline at end of file". Following the words of the warning, I added a newline at the end of the file and tried it again...with the exact same result. Whether I try one newline or twenty, it never seems to compile. </p> <p>I attached the simple, and still unfinished, file below (Except imagine there is a blank line at the end of it. This noob can't get it show up in code view): </p> <pre><code> #include &lt;iostream&gt; #include &lt;string&gt; using namespace std; int getInput(); void displayFactorial(int); int main() { int number = getInput(); displayFactorial(number); return 0; } int getInput() { int userNumber; bool okNumber; while(okNumber == false){ cout &lt;&lt; "Please eneter a number in the range of 1-10"; cin &gt;&gt; userNumber; if(userNumber &gt;= 1 and userNumber &lt;=10){ okNumber = true; } else{ cout &lt;&lt; "Incorrect number" &lt;&lt; endl; } } return userNumber; } void displayFactorial(int number){ string displayString = number + "! ="; int total; for(int i = 0; i&lt;=number; i++){ //displayString += " } cout &lt;&lt; displayString; } // File ended the line above this (with a new line. This line added by Martin so it shows) </code></pre> <p>Any idea what could cause that warning if it's not the newline?</p>
