Assignment is about selection sorting in c# , the part i don't get is
Run your program for N = 1000, 2000, 5000, 10000, 20000 and 50000. Note
down the number of comparisons for each N and draw a line graph (with N as
independent variable and comparison count as dependent) using Excel.
How do i take c# data and use it in excel to make a line graph i have no idea.
Are you sure that your assigment is telling you to put your results in Excel programmatically? I read that as record the data on your own, type it into Excel, and generate a line graph.
