PAT 1004 score ranking helps you look at the code. I don't know where the error is. I submitted it partially correctly.

1, n should be dynamic. Now you have a maximum of 100 (non-fatal)
2. in C language, the array starts from 0 and the loop starts from 0 (non-fatal)
What does "one submission is partially correct" mean?
 
Store and sort scores using a C # Two-dimensional array

The program is successfully debugged under win-tc and Dev-c ++. This program is rewritten based on your source program:

# Include "stdlib. h"
# Include "conio. h"
