// Lab D// By Perry Huang// 11/27/2007/*Notes & Comments:- string.h is required for memcpy- math.h is required for roundf function- arrays were used to maintain sanity- flush used after scanf's- numbers[10] contains 10 numbers that are from user input- rounded[10] is same as numbers[10], but rounded with roundf after- average carries the average of the values in numbers array*/#include <stdio.h>#include <math.h>#include <string.h>#define FLUSH while(getchar()!='\n')float input();float findaverage(float *numbers);void output(float *numbers, float *rounded, float, float);void printasterisk(float);void repeat();void main(){	float numbers[10], rounded[10], average, raverage;	puts("Hi.
