c++ - Reading in a specific column of data from a text file in C

Question

My text file looks like this:

987 10.50   N   50
383 9.500   N   20
224 12.00   N   40

I want to read only the second column of data. How would I got about doing this?

Answer 1

You can't just read the second column without reading anything else.

What you can do is read all the data, and ignore everything but the second column. For example, read a line of data (with std::getline) then from it extract an int and a double, but ignore both the int and the rest of the line.
