Assignment Statement Considered Harmful
-
I believe one of the early programming languages allowed literals to be overwritten in code with the assignment operator.
Need custom software developed? I do custom programming based primarily on MS tools with an emphasis on C# development and consulting. I also do Android Programming as I find it a refreshing break from the MS. A man said to the universe: "Sir I exist!" "However," replied the universe, "The fact has not created in me

this just in: functional language programmer thinks functional languages are better than imperative languages and tries to prove it by asserting that imperative languages programmers don't understand what they're doing; hilarity ensues.
I just wonder where functional programmers store the result of your statement.

What do you mean? I've literally been swimming in it.
He said, "Boy I'm just old and lonely, But thank you for your concern, Here's wishing you a Happy New Year." I wished him one back in return.
Mercury can be lethal in large quantities too, but not if those large quantities are on a planet you are not on. All depends on how you use it. It can be lethal in large quantites if inhaled or injected (or shot out of a dihydrogen monoxide gun that propels the substance at a sufficient velocity into your brain).

Actually, that could be lethal too, if the gravity is sufficient to cause a sheer force that rips you apart.

I've had four beers, but that makes sense. A literal is basically an anonymous object. The following is not allowed in C#, but I think it illustrates the concept of assigning to a literal quite nicely, and we all know how promiscuous older languages were compared to our beloved.
var lit = new {Name = "Brady"}; lit.Name = "Ennis"; -

Ok, next month's competition Write a piece of code with the following condition a. You can't use
goto(very simple) b. You can't useifstatement c. You can't useforloops d. You can't use assignment statements. Good luck :rolleyes:Yusuf May I help you?

//#include <iostream> //wait... we don't any of those!
int main()
{
return; //usage of return is NOT yet banned.
}It's time for a new sig. Seriously.

After we figured out that goto is bad[^] and established that if statement is not much better[^], and of course for loops should be avoided at all cost[^] it is time for another logical step in that direction: ladies and gentlemen I give you Assignment Statement Considered Harmful[^].
On a (somewhat) related note, I found Big Ball of Mud[^] to be an excellent read. /ravi

An excellent read, Ravi! :-D Fortunately, all of my projects are based from inception on the BBoM architecture, which saves me loads of time by never refactoring.

var lit = new {Name = "Brady"}; lit.Name = "Ennis";The assigning to a literal bug refers to
4 = 5;
Being legal code and replacing the binary value of 4 with 5 break all logic based one that literal.
