#include <iostream>
#include <conio.h>
int main(int argc,char **argv){
    int numbers[20];
    float average,total;
    for(int i=0;i<=19;i++){
        //active breakpoint
        numbers[i]=i;
        total+=i;
    }
    average=total/20;//comment
    cout<<"total:"<<total<<"\nAverage:"<<average;
    getch();
}
