933,418 | 933,419 | Difference Between Javascript Wrapping Methods | <p>It is generally accepted that Javascript code should be wrapped in a function to prevent leaking to the global scope and just assign whatever you need outside of each function to the <code>head</code> object (<code>window</code> in web browsers).</p>
<p>I've seen two primary methods of this in the wild:</p>
<p><strong>Method 1:</strong></p>
<pre><code>(function() {
// code here
}).call(this);
</code></pre>
<p><strong>Method 2:</strong></p>
<pre><code>(function() {
// code here
})();
</code></pre>
<p><strong>Method 1</strong> is from compiled CoffeeScript code, and <strong>Method 2</strong> seems to be the preferred style for jQuery plugins:</p>
<p>Modified Method 2 for jQuery:</p>
<pre><code>(function($) {
// JQuery Code
})(jQuery);
</code></pre>
<p><strong>Question:</strong> What is the difference between <strong>Method 1</strong> and <strong>Method 2</strong>? CoffeeScript likes to focus on conciseness, so I figure there must have been a reason for the people behind CoffeeScript to choose <strong>Method 2</strong> over <strong>Method 1</strong>.</p>

299,734 | 299,735 | Looped function calling not looping correctly! (C++) | <p>I am doing a homework for my Systems Programming course.
I have to implement a University simulation.
I have a Course abstract class, and child class of it ComputerScienceCourse (and a bunch of other child classes that don't affect what I'm going to ask).
and I have a Student abstract class, and child class of it ComputerScienceStudent (and a bunch of other child classes that don't affect what I'm going to ask).
In the ComputerScienceCourse child class there is a function:</p>
<pre><code>void teach(){
for(i = all students that take this course [stored in a vector of pointers to Student objects, which is a member field of the CSCourse child class, called students]){
this->students.at(i)->study(*this);
}
}
</code></pre>
<p>This function calls study function for all students that have taken this class. The function is a member function of child class CSStudent</p>
<pre><code>void study(Course &c){
if(this->failedclass){
c.removeStudent(this)
}
}
</code></pre>
<p>Now when I check the output, the loop in the teach function does not call the study function for all the students within.
For example, if I have 4 students doing this course, sometimes it would call the study function of only the first three, sometimes it calls the function for the first and the last student... varies.
What could be causing the for loop to not call ALL students study functions?!
Here's the full code for the teach function:</p>
<pre><code> for(unsigned int i=0; i<this->studentMembers.size(); i++){
this->studentMembers.at(i)->study(*this);
}
