Error 1 error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

  This program will ask the user for the  number of accidents for that year.
It will then use two functions to calculate the area with the lowest
accidents and displays the name of the area and the number of accidents.

long double main (999)
Change #include <cstring> to #include <string> .

I changed that and it now compiles. But mu out put it wrong and I have an error:
Warning 1 warning C4715: 'numAccident' : not all control paths return a value

it is located somewhere in the numAccident function.

Also for some reason I am not getting the correct answer even though it looks correct.

If they enter < 0 for accidents, you output an error message but don't return a value from the function. You could prompt them to re-enter, or maybe just return a value of 0.


Edit: Check the logic in the findLowest function.
Line 77 would imply that central is the highest number. But you output that it's the lowest.

This function is done the correct way, I think, it still doesn't work correctly.

Your if statements are defective. e.g. Line 9: What does the relationship between south and east have to do with the cout statement on line 11?

Line 11: Which are you trying to display? You state "Central region", but you display the count for north.

Shouldn't this be: 
1
2
3
4
 
if (north < south && north < east && north < west && north < central)
    {    cout << "The North Region came in the lowest with " << north << " accidents." << endl;
        cout << endl;
    }

etc... for each of the other regions.

What happens if two regions are tied for lowest?
