hello everybody.
i m stuck in logical approach to an algorithm flow.
inside code there is an if-then statement i want to be checked once, after return true then dont check again.
in details

C++
while(true)
{ do something     (A)
  
  if(something)
     {do something  (B)
     }

 
 do other things   (C)
}


during the process within while loop, conditions B may turn true multiple times but i want, once is true, always jump from A to C without checking the B again.

What I have tried:

i tried to insert a boolean variable that is turned to true once B statement is checked, but no success.
this variable is set outside the scope of if statement (B) and is not possible

If I understand correctly, then this should work:
done = false

while(true)
{
   do something (A)

   if(!done && something)
   {
      do something (B)
      done = true
   }


   do other things (C)
}

Grazie.
Try:
C++
bool doneOnce = false;
while(true)
   { 
   DoSomethingA();

   if(!doneOnce && something)
      {
      DoSomethingB();
      doneOnce = true;
      }

   DoSomethingC();
   }

Just an advice: Learn better coding style.
Coding style is the way you write code, a good coding style makes your code easier to read, and in large code base, it matters.
Never try to save a keystroke by grouping things on same line, particularly never put code after a '{' , it makes code more difficult to read.
Some professional programmer editors (like Eclipse) have a code formatting feature.
C++
while(true)
{
    do something     (A)
    if(something)
    {
        do something  (B)
    }
    do other things   (C)
}

or
C++
while(true) {
    do something     (A)
    if(something) {
        do something  (B)
    }
    do other things   (C)
}


Advice: Learn to indent properly your code, it show its structure and it helps spotting structures mistakes.

Professional programmer's editors have this feature and others ones such as parenthesis matching and syntax highlighting.
