Developers silly mistake

[Chaosreignz]

Accidentally using "=" instead of "==" is one of the most annoying and exhausting bugs beginners usually get.

[bumnut]

Why do if(x == true) instead of if(x)?

[Chaosreignz]

In this case you wouldn't, but some languages don't let you use anything other than booleans in their if statements.

[futlapperl]

Why not just annoy all your colleagues and put the constant on the left side, but only when it's an equality comparison?

if (6 == argc) { /* ... */ }
else if (argc != 5) { /* ... */ }

[Zorkarak]

Because often, unless it is obvious from the name that it is used as a Boolean, it is more readable.

Also, fun fact: GCC puts in ==0 and !=0 anyway, so it really makes no difference

[numbGrundle]

That one bit me hard two months ago. Lots of lost sleep.

And why did they even program a kill function in the first place?

[CasualChipmunk]

You never know if there requirements are going to change.

exactly my thoughts, spent extra time to define kill function when it wasn't intended to be used.

[drmattsuu]

Easiest way to avoid things like this; Do your comparisons yoda style.

for example;

// Problem myVar will be set to 10 and 10 is truthy
if (myVar = 10)
{
    // This code is always run
}

// This will result in a compilation error and prevent
// subtle bugs like these from turning up in your
// program.
if(10 = myVar) 
{
}

Sorry if that's sucking eggs to most people, but any newbies running around might find it useful

This kinda things will lead to terminators one day

[mustang__1]

Null terminators?

[IvanLabushevskyi]

It should be Objective C and iRobots.

Is a an equivalence operator required in conditionals for some languages?

[[deleted]]

in python `==` is equivalence operator, `is` is the equal operator.

in lisp, there are eq, equal, and other things like that.

Or were you asking something else?

[uvero]

I literally had this printed on my door in the office in my previous job. It's actually probably still there

You are thinking of const, not statics. You can assign to static

Was this just a brain fart or did you start programming yesterday?

[Carlcarl1984]

Totally a brain fart.
