#In the main function, input a set of (10) C language scores into the array score [], and output as shown in the figure The main menu shown in the figure is called according to different selections The corresponding functions are realized by writing functions: (1) Output average score; (2) Rank and output the scores; (3) Output scores lower than the average, and the number; (4) Output pass rate (5) Enter a score value to find, output found or not found. (6) After sorting, enter a score value, add it to score [] and keep the order.
