My Solution

#include<stdio.h>
int main(void){
    int num1=0,num2=0,i=0,count=0,sum=0;
    printf("정수 2개를 입력하시오 : ");
    scanf("%d %d",&num1,&num2);
    for(i=num1;i<=num2;i++){
        if(i%3==0||i%5==0){
            sum+=i;
            count++;
        }
        else{
        }
    
    }
    printf("sum : %d\n",sum);
    printf("avg : %.1f",(float)sum/count);
    return 0;
}
