You can tell which is the independent variable and which is the dependent variable by changing the equation into an "if/then" statement. Example: y = 3x In this example, x is the independent variable and y is the dependent variable. If you give me x, I will tell you y. If x = 1, then y = 3 If x = 2, then y = 6 So you give me the independent variable, and then I will be able to determine the dependent variable.

Each value of x, when substituted in the equation, will give a true statement.

Foreach is for an IEnumerable, not just an array (unless you are using C# 1.1 or earlier). A collection (List, Dictionary, etc) can also generate a sequence from foreach-statement. In fact, if you have a class that is NOT an array, but it implements all the required methods of IEnumerable, it may be applied as:public class Storage: IEnumerable {...}Storage myStorage = new Storage();...Foreach (Thing stuff in myStorage){...}
There is no 'foreach' in C
Assuming your data store implements the "IEnumerable" interface (or the IEnumerable generic interface) foreach (type arg in datastore) { ... } So, for example, if you have a List, it would be List list = new List() ... foreach (string val in list) { Console.Out.WriteLine(val); }
The foreach construct simply gives an easy way to iterate over arrays. Foreach works only on arrays (and objects).
give the example of general statement were no streetrees
foreach can simply replace for loop. for ex in perl, if you need to copy display an array, it will take only foreach $var(@arr). then print $var. no need of incrementing the index of array like for loop.

positive example
difference between for and for each loop..?The for loop executes a statement or a block of statements repeatedly until a specified expression evaluates to false. there is need to specify the loop bounds( minimum or maximum).int j = 0;for (int i = 1; i

I understand the IEnumerator/IEnumerable methods and properties and also how they are interrelated. But I fail to understand from the foreach loop perspective. Say for example, if I say the following line of code, how does the compiler look at foreach loop and break it down to IEnumerable/IEnumerator for every occurance of foreach loop in your code. In other words, what happens under the hood? I tried to go through couple of articles on the web. But they were NOT looked from the foreach loop perspective or I might have failed to understand. Could somebody explain with the example or direct me to any articles that explains clearly. All help is greatly appreciated.Answer: To keep it short the compiler doesn't do much. It just translates the foreach code into a while under the hood. Here's an example: List list = new List; ........ foreach(int item in list) { //Do stuff} Becomes: Enumerator enum = ((IEnumerable)list).GetEnumerator(); enum.Reset(); while(enum.MoveNext()) { int item = enum.Current;//Do stuff} or something very close to that. The acual code compiled most likely has a try / finally block around the while to dispose the enumerator
A fallacy is a statement that is in error or not correct. "The earth is flat" is a fallacy.
