This is a very simple question: How can I read .txt file and save to a vector using c++? I've 9 data stored in a txt file separated by tab and I want to save this to three different Vector (I'm using Eigen library). the 9 data are this:
-468.01 198.74 -123.9 -471.67 195.41 46.878 -471.39 111.84 45.518
Someone can help me? Thanks in advance!
