arrayAndFunction.c

#include <stdio.h>
/*
Your program should first read, from the user input, the number of players participating 
in the game. There are never more than 10 players in the game. Next, your program should 
read the current scores of each player and store them in an array. Then you should call the 
function behind(), to which you pass as a first argument, the array holding the player's scores, 
and as a second argument the number of players in the game. The function behind should replace 
the scores stored in the array with the number of points by which each individual player is 
behind the top-scoring player.

Input

Output
