Answer 1

#include<stdio.h>
int main(){
    int a[15]={20,0,10,55,90,0,60,40,35,85,100,200,30,0,5};
    int num=0,sum = 0,temp;
    
    for(int i = 0;i<15;i++){
        for(int j = i+1;j<15;j++){
            if(a[i]<a[j]){
                temp = a[i];
                a[i]=a[j];
                a[j] = temp;
            }
        }
    }
    
    for(int i = 0;i<15;i++){
        if(a[i]!=0){
            sum+=a[i];
            num++;
        }
    }
    printf("捐款人数:%d 捐款人平均捐款:%d \n",num,sum/num); 
    for(int i = 0;i<15;i++){
        printf("%d ",a[i]);
    }
    
    return 0;
