I made a program that calculates the average of an array, but I'm getting wrong answers. When I enter 10 9 8 7 6 5 4 3 2 1, the average is 4199211. Are there any errors in my program? Thanks

Code:#include <stdio.h> double average (int ary[ ]); int main (void) { double ave; int ary[10]; int numbers; printf("Enter 10 numbers: \n"); for (numbers = 0; numbers < 10; numbers++) scanf("%d", &ary[numbers]); ave = average(ary); printf("Average : %d\n", average); system ("pause"); return 0; } double average (int ary[ ]) { int sum = 0; int numbers; for (numbers = 0; numbers < 10; ++numbers) sum += ary[numbers]; return (sum / 10); }
