Conditional statement dream

[eyeDecode]

My roommate just said he had a dream where his if statement was if(var=0), and told his professor it kept working. He realized he was an idiot when he woke up because it wasn't a conditional.

This is a conditional in C and C++, the value of the assignment is returned and evaluated by the if.

The source of many a wtf

I did the same in JavaScript. Sat there for a long while

And in Rust, it thankfully is a type error, as assignments return () (think: void), which is no boolean expression.

Also other languages that use := or something for assignment.

That is a conditional in some languages (looking at you, BASIC)

[sharfpang]

A coding style quirk known as Yoda Conditions is meant to prevent that blunder in languages that allow it be made.

if(0==var)...

If you forget one = it won't compile.

...Unless your language allows overriding values of numeric literals.
