C++ I believe my GIS findParcelName function is not reading the next line of simply-polygon.txt provided below. If you look at the output it appears to be checking the first polygon but it reads a 0 for the second one so I think it is not reading the next line in the sample-polygon.txt file.

Photo of error output:

simple-polygons.txt:

squareParcel 0 0 0 2 2 2 2 0 //READS squareParcel wideRectangleParcel 0 2 0 4 6 4 6 2 //DOES NOT READ wideRectangleParcel
