New line added in loop

bumski (4)
When adding stucts to a vector, middle elements will have a blank line before the getline field output. When trying to compare fields will cause the comparison to fail, causing the program to crash. I am having problems with the nutrient struct specifically, the only difference that I see between the two is the delimiter.
