Expected unqualified-id before numeric constant?

Question

I'm getting errors on lines `102, 115, and 128`. What am I doing wrong? It says: Expected unqualified-id before numeric constant and I don't know what that means. I've tried to fix this for a week now, and it's due in my C++ class this coming Wednesday. I could really use some outside advice here. What am I doing wrong: ``` #include #include #include #include #include using namespace std; double qMeter = 0; double hMeter = 0; double oneMeter = 0; int solDay = 0; string garbage; string localTime; string decSol; ifstream input; ofstream output; //function prototypes double low(double lowTemp); double high(double highTemp); float average(double avgTemp); int main() { input.open("curiosity234x.dat"); //opens input data file output.open("output.dat"); //opens output data file for (int i = 0; i < 4; i++) //gets rid of the first four lines { getline(input,garbage); cout << endl; } while (!input.eof()) { int count; double newOneMeter; double n…

Accepted Answer

Errors on line 102 and 115 are due to the fact that you have a comma in `10,000`, but it should be `10000`, the comma can not be used as a numeric separator. What you are actually using is the comma operator which evaluates it's expressions from left to right and only returns the last one. So in this case:

```
int test = 10,000;
           ^  ^
           |  Expression 2
           Expression 1
```

since `=` has higher precedence it happens first and your are left with a syntax error, on the other hand:

```
int test = (10,000);
```

would have resulted in the value `10` being discarded and octal literal `000` being assigned to `test`.

The final error on line 128 is due to the fact that count is local to `main` but you are trying to use it in `average`, you need to pass `count` as a second paramter.
