Read the first line – the one with the headings – separately. Then for each subsequent line, use the white-space delimiters to read DEC, OCT and so on. Use std::istringstream if necessary.
Consider using a struct with data-members corresponding to the different numbering systems and read into these fields one by one from the file. Store struct objects in a std::vector<Numbers> for e.g.
Then conversion from one numbering system to another would be equivalent of finding the struct instance in the vector by the data-member that you want to convert from and listing its corresponding data-member that you want to convert to
