I'm stuck at the point where I'm supposed to enter scores and the program will eliminate the two lowest scores for me.

For instance I enter
1 2 3 4
for assignments 1-4 respectively, the result will come out right.
But if I enter
9 6 7 8
only the first two assignment results will show but not others.

What seems to be wrong here guys?

Thanks.

The code in itself is quite poor. In addition it's not clear to me what the program SHOULD do. Can you explain what the input is supposed to represent, when and which scores should be elinated and other relevant information? When entering the values you supplied the application outputs:

Assignment 2 first score has been eliminated.
Assignment 3 second score has been eliminated.

Which I guess is what you don't want. I don't understand the logic of your application though.. If I were you I'd re-write it from scratch and set it up better. A good start would be is to identify subproblems that could be contained in a function.
