the compiler is giving me a fatal error because of the bool meet[] array but i dont know how to fix the error, unless im missing something obvious

[keskiverto]

What error and on what line? Why do you try to store characters 't' and 'f' into a bool variable, even when agnophilo's post did show the use of the boolean keywords?

You still add to to a an uninitialized variable, and you add to it regardless of what the comparison shows. An undefined number + 1 is still an undefined number. It would be undefined number + SIZE, if you would not call return inside the loop.


You don't seem (for whatever reason) able to pay attention to what we tell you.

I didn't mean to negate your responses, I am trying to balance multiple things at a time, I will reread my code and these responses and put together what I think is the correct code and re post it again here, as for the last remark my apologies again no need for the what seems to me rudeness. I appreciate the help you guys have given

"I have that code typed in but then what do I return?? Im confused because I cant return the array meet[i] can I?"

Why not? i is a local variable that just modifies which index meet[] points to, meet is not a local variable and you can assign it without having to return a value, or if you put it in a function you can pass it by reference. You are confusing the return statement which replaces the function call with a value produced by the function with an assignment operation which assigns a value to a variable. If a function says variable_x = 1; then variable_x will equal 1 until the function is finished executing if variable_x was declared in the function (or the initialization section of a loop) or it will still have the value assigned after the function/loop executes if variable_x was declared outside of the scope of the function/loop. The code I gave preserves the value of everything but variable i after the loop executes.

"after the true/false values get assigned to all of the indexes I need to tally up the true's and output that integer number."

So either make a loop that does that at the end or make another if-then statement that does numberoftrue++ or numberoffalse++ etc.

Thank you for baring with me on this, my apologies again. I will implement the code and come back with results

[agnophilo]

You're welcome, and no need to apologize, it's what the forum's here for. I am a newbie too (am about 3/4 of the way through the tutorial). Everything in programming is hard to comprehend at first, then it gradually becomes clearer. Sleeping on it helps a lot.

this is what I have after rereading this post.

I cant figure out the above and below part still and I have reread the post twice

[agnophilo]

What don't you understand?

[TECKSPEED]

how to tally then output the number of trues in the meet[] array. It reads if the current index of sales[] is < the current index of the targetNumber[], the current index gets false and else if sales[] is > targetNumber[]

but after that how do I tally the trues up and then output them?

do you get what im trying to say??

int compareAboveArrays(float &Numsales,float sales[], float targetNumber[], bool meet[], float SIZE, float &salesAverage, int NumOfFalses)
{
  int NumberOfFalses = 0;
  for (int i = 0; i < SIZE; i++)
    {
      if(sales[i] < targetNumber[i])
        meet[i] = false;
      else
        meet[i] = true;
 }
  for(int j = 0; j < SIZE; j++)
  if(meet[j] = false)
    NumberOfFalses++;
  else
    12 - NumberOfFalses;
  return NumberOfFalses;
}
