so I've been trying to write this program that takes the data from a file and outputs the year the rainfall how much it is below/above the average, the average raifall and the std deviation and for some reason I get three

```
C4552 warnings:'>': operator has no effect on three for loops.
```

Help is highly appreciated :(
