What D.J.Мамонт – «Финская румынка» - Красная Плесень - Союз популярных пародий ЖАРЕНАЯ ТРИДЦАТКА don't understand is how 'bit--' can be an exit condition.
Please help me understand how this code works I tested it, and it is valid. In C, a value of zero evaluates to "false" in a boolean context. So when bits-- evaluates to 0in the context of the loop it evaluates to "false" and terminates the loop. It will output "False", because --x evaluates to 0, which is Walk Free - Exit Condition - Bite Down Hard / Impact Time in a boolean context.
All conditions basically boil down to checking whether something is 0 or not. So that loop will break when bits is 0. To match the for loop syntax, it gets converted to a boolean expression, which means it is true if bits!
In fact, the condition is identical to bits! As other said, in C, you can use integers as condition - 0 or falseanything else for true. When the -- operator comes after the variable, it decreases the variable, and gets the previous value of it. So, the loop will exit after that bits will been decreased from 0 to Nice way to loop through an array Since in c, array of bits variables is been indexed from 0 to bits Learn more.
Understanding the exit condition of Walk Free - Exit Condition - Bite Down Hard / Impact Time for loop Ask Question. Asked 7 years, 10 months ago. Active 7 years, 10 months ago.
Viewed 2k times. This is the syntax for a for loop that I've always known: for variable initialization; condition; variable update What I don't understand is how 'bit--' can be an exit condition. Thank you. This is what C programmers are cursed for!! Producing code that does something but no one understands it anymore. Don't try to write code like that!! So why should new code in any language be written for Walk Free - Exit Condition - Bite Down Hard / Impact Time who do not understand the language?
Arkku I also understand the code, but you must agree it's not good coding style. Writing the for-loop in a "standard" manner makes it more readable to anyone, not just the cracks. As for uno, it's not descriptive but considering the simplicity of the code fragment it may not need to be For example, if this is a routine to convert an uint to a string in base 2, what would you call u instead?
Of course we don't know if this is part of such a function where u has such an obvious role. Arkku I would maybe call it numSourceStr or something like that. I'm more on the "modern" side here, but I can live with that. Charles Salvia Charles Salvia Ok, I had suspicions that that was the case.
Charles, you are right, but --x is not the same as x If you change the code above to x-- it will print Death Angel - Sonic German Beatdown - Live In Germany The point is simply to demonstrate that expressions which evaluate to zero are considered "false" in a conditional context. Seth Carnegie Seth Carnegie Actually, in C everything is considered true except zero I think.
