### Question: Boolean While Loop...

My friend wrote this code for me to understand some topics I asked him about. For his sake (i've asked far too many questions) I want to present this question here.

Could someone explain to me in human language what LINE 14 is proclaiming when it exclaims:

`while (out_of_order){`

I'm not what the while statement is declaring here.
I'm new to boolean logic, so please be as specific as possible. I understand that the variable is being held as true, but I don't understand what the conditions mean for the while statement.

1. Is the while statement saying "loop while out_of_order is false?" If that's the case then...

2. Why is it then said that out_of_order is false during the IF function?

Here's the rest of the code (without some parts on either end...):

 ``1234567891011121314151617181920`` ``````#include using namespace std; int main() { int v1, v2, v3; // variables for type int cin>>v1>>v2>>v3; // reading v-variable bool out_of_order; // // Sort it into ascending order // where v1 < v2 < v3 out_of_order = true; // MIGHT be out of order variable is BOOLEAN while(out_of_order) { out_of_order = false; // out_of_order FALSE if if(v1 > v2) { // if v1 is GREATER THAN v2 int temp = v1; // temp <- v1 v1 = v2; // v1 <- v2 v2 = temp; // v2 <- temp out_of_order = true;``````

while(true). its the same as while(out_of_order == true)
@DTSCode,

But is while(true) the same as while(out_of_order)?
If and only if out_of_order holds true...

kind of. every loop condition and if branch test will only execute if it evaluates to true as out_order_does. if it was false you would have to make the condition !out_of_order or out_of_order == false
Thanks @kevinkjt2000,

But here's what confuses me. What does that mean for the whole while function? Does that mean the while statement runs until the out_of_order is false?
@DTSCode,

Thanks! That makes sense.

SO, the while function loops until the out_of_order variable is considered false. Once it is considered false, the next line of code executes?

while isnt a function. its a loop. and all of the code between its start ({) and end (}) bracket execute until its false. then the next peice of code executes
@DTSCode,

Ok, last question:

Do the IF statements run at the same time?

no.
Thanks!
