Sum of loop output in float

[maureen22]

Hello I need help on how to compute the loop output in float

  float num=1.5,sum;

do
{
cout<<num;
cout<<endl;
num+=1.5;


}while(num<=9.0);

sum+=num;
cout<<"Sum: "<<sum;

The output of my code is:
1.5
3
4.5
6
7.5
9
Sum: 10.5
The output I'm looking for is this:
1.5
3.0
4.5
6.0
7.5
9.0
Sum: 31.5

sum+=num;
Try putting this before the loop starts.

Then try putting it inside the loop.
Think about whether it should go before or after the adjustment of num.

Ohh it works when it's in the loop how? But another problem is how can I make the 3, 6, and 9 into 3.0, 6.0 and 9.0

If only there was something you could do to the s/w.

Maybe, just maybe

num+=1.5;
sum+=num;
cout << "DEBUG: num=" << num << ", sum=" << sum << endl;

When you've understood, you can delete the debug line.

But setprecision doesn't add .0 to the whole numbers.
