        }
        else if((w > 1000) && (w < 1000000))
        {
                 w = w/1000;
                printf("Your windmill generated" %.1f " watts today!", w);
        }
        else if(w > 1000000)
        {
       		w = w/1000000;
        	printf("Your windmill generated" %.1f " watts today!", w);
     	}
}

I don't see what's wrong with it. It keeps reprompting on the second while loop even though I don't want it to reprompt, just go back to nameplate capactity prompt. Let me know if you see what my problems are and ask me if you need any clarification.

Looks like you have an infinite loop.
1

3
 
int i=0;
...
while (i==0)

The variable i never changes from being 0.


Also.

cout << "Insert Generator's name capacity in watts\n";
cin >> g;
{ <- //What purpose do these two braces serve?
		if (g < 300)                    
       		{
               		cout << "Nameplate capacity must be between 300 and 8,000,000 watts.\n";
        	}
        	else if (g > 8,000,000)
        	{
                	cout << "Nameplate capacity must be less than 8,000,000.\n";
        	}
		else

			break;
		}
} <- //What purpose do these two braces serve?
