I want to check whether a value is equal to 1. Is there any difference in the following lines of code
Evaluated value == 1
1 == evaluated value
in terms of the compiler execution

boost::operators automatically defines operators like + based on manual implementations like += which is very useful. To generate those operators for T, one inherits from boost::operators<T> as shown by the boost example:
class MyInt : boost::operators<MyInt>
I am familiar with the CRTP…

I have an enumerated type that I would like to define the , <, =, and <= operators for. I know that these operators are implictly created on the basis of the enumerated type (as per the documentation) but I would like to explictly define these operators (for clarity, for control, to know how…

I'm creating a stack oriented virtual machine, and so I started learning Forth for a general understanding about how it would work. Then I shortlisted the essential stack manipulation operations I would need to implement in my virtual machine:
drop ( a -- )
dup ( a -- a a )
swap ( a b -- b a )
rot…

I have two variables:
char charTime[] = "TIME";
char buf[] = "SOMETHINGELSE";
I want to check if these two are equal... using charTime == buf doesn't work.
What should I use, and can someone explain why using == doesn't work?
Would this action be different in C and C++?

Why am I getting this result?
[TestMethod]
public void nan_test()
{
Assert.AreEqual(1, double.NaN, 1E-1); <-- Passes
Assert.AreEqual(1, double.NaN); <-- Fails

I understand that, with a singleton situation, you can perform such an operation as:
spam == eggs
and if spam and eggs are instances of the same class with all the same attribute values, it will return True. In a Django model, this is natural because two separate instances of a model won't ever…

I'm basically building a simple list, and one of the items in the list is selected. I'm accomplishing this by having a "selected" class applied to whichever item I want to have selected. I have two buttons that go forward and backward which traverse this list. However, when the user gets to the…
