C语言程序设计大题1

#include
void  TestFunc(); 



int average_num(double a[],int n,double b[])
{
  
  
  
  
  
  
  
  
}


main()
{
  double a[100],b[100];  int n,i,num;
  printf("input n:");
  scanf("%d",&n);
  printf("input %d data:n",n);
  for(i=0;i 
答案
 
int i,m=0;
  double avg=0;
  for(i=0;ia[i])
		  b[m++]=a[i];
	
  return m;
