1. ## Wind Simulation Project Please a little help !

hi guys,

I'm trying to finish my wind smulation project but I'm having problems.

What I'm doing is creating a for loop to display from

0 seconds to 3600 seconds or 1 hour of wind simulation

My first Column displays the Time, and the second column displays the wind result which is a calculation from three inputs.

cin >> Avg_Wind;
cin >> High_Gust;
cin >> Low_Gust;

Upper_Limit = Avg_Windi + High_Gust;
Lower_Limit = Low_Gust;

Avg_Wind = rand_float (Upper_Limit, Lower_Limit);

What I need to do is make some kind of calculation that would increased by 10 the Avg_Wind for a period of 300 seconds.

I created a function on the botton but for some reason it doesn't increased by 10 for a period of 300 seconds and but adds 10 to the wind result for the whole hour
Please give me a hand if you have more questions let me know and I will try to explain better .

Thanks Here's what I have so far
Code:

}
}```

2. > cout << setw(4) << i << " " << Small_Storm(Avg_Wind) <<

if(i<300)cout<<set(4)<<i<<" "<<small_Storm(avg_wind).

Code:
```double Small_Storm ( double Storm ) //Returns a value and Adds 10 mph to the Average for five minutes of Storm
{
int Storm_Time = 300;

for ( int x = 0; x < Storm_Time; x++)
{

return Avg_Wind = rand_float (Upper_Limit + 10, Lower_Limit + 10);

}

}```
the loop is not required.

and u r not passing the value of upper_limit or lower_limit
