#include<stdio.h>
int main(void){
    int num=0,count=0,sum=0;
    printf("정수를 입력하시오 : ");
    while(1){
        scanf("%d",&num);
        count++;
        if(count>20 || num == 0){
            count-=1;
            break;
        }
        else{
            sum+=num;    
        }
        
    }
    printf("sum : %d avg : %.d",sum,(int)sum/count);
