Reading a file and output selected data - c++11

Question

I'm trying to read data and output only selected data from a CSV file(Date, time and S(speed). My program is able to run but it loops in a weird way. Line 1, than Line 1 and 2, than Line 1,2 and 3 and so on and so forth. The final record that is shown in the program is also incorrect(0/3/2016 23:50). Need some guidance to rectify this problem.
Sample data in notepad format below. It contains thousands of line but only pick the last 3 lines to illustrate my problem. Ignore the "Line" below, it's just to tell you which line is in excel format. Line 1 is the header which i ignore, follow by the data.
Line 1:WAST,DP,Dta,Dts,EV,QFE,QFF,QNH,RF,RH,S,SR,ST1,ST2,ST3,ST4,Sx,T
Line 2: 31/03/2016 23:30,11.4,257,11,0,1012.9,1016.4,1016.5,0,63.5,5,13,26.4,25.8,25.6,26.1,7,18.48
Line 3: 31/03/2016 23:40,11.4,250,15,0,1012.9,1016.4,1016.5,0,64.7,5,10,26.4,25.8,25.6,26.1,6,18.19
Line 4:31/03/2016 23:50,11.4,243,5,0,1012.7,1016.2,1016.3,0,65.8,3,11,26.3,25.8,25.6,26.1,5,17.95
