I have to print out the numbers -2.3 to 2.9 in increments of 0.4, and then add the poss and neg number
EX:
-2.3 -1.9 -1.5 -1.1 -0.7 -0.3 0.1 0.5 0.9 1.3 1.7 2.1 2.5 2.9
Sum of negative values: -7.8
Sum of positive values: 12

i have gotten a little father than this but my code is all over the board.

#include <iostream.h>

int main() {

 

  for (float counter=-2.3; counter <= 3.0; counter+=.4)
    cout << counter << " ";



return 0;
}

add a float counter and then add the value of counter to it within the loop that begins on line 7 of the code you posted.

>> but my code is all over the board.
Looks ok to me, just add the code I mentioned above and you have the answer.

You are very close. You just need to add a couple of things to your loop.

#include <iostream>
using namespace std;
int main()
{
  // The sum of no numbers is zero, so...
  float sum_of_positive = 0.0;
  float sum_of_negative = 0.0;

  for (float counter=-2.3; counter <= 3.0; counter+=.4)
  {
    cout << counter << " ";
    // [B]todo: if counter is less than zero, add it to the sum_of_negative[/B]
    // [B]todo: same kind of thing for positive numbers[/B]
  }

  // [B]todo: print out your sums here[/B]

  return EXIT_SUCCESS;
  }

Hope this helps.

[EDIT]
man, too slow again...

fooey.

If youre still lost heres some code you can use:

#include <iostream>
using namespace std;
int main()
{
  
  float sum_of_positive = 0.0;
  float sum_of_negative = 0.0;
  float counter;

  for (counter=-2.3; counter <= 3.0; counter+=.4)
  {
    cout << counter << " ";
	if (counter < 0)
		sum_of_negative +=counter;
	else
		sum_of_positive +=counter;

  }

  cout << "Sum of negative values: " << sum_of_negative;
  cout << "Sum of positive values: " << sum_of_positive;

  return 0;
  }

How to cheat! It's an important part of life.
And what does he learn when you do the work for him?

Nobody learns if you just give them answers. My post was as close to it as I dare go.

The trick to programming hasn't anything to do with syntax or language or loops or anything. It is thinking about the problem.
