输入<> 0时“执行”循环

Question

Write an application that keeps inputting an integer from the user until zero is entered.
The program will calculate and display the average of the numbers, and display the largest and smallest of the numbers.
Zero is not to be included in the average, largest or smallest printouts.

I tried it and got this far:

#include <iostream>
using namespace std;

int main () {
    string str;
    do {
        cout << "Enter text: ";
        getline (cin,str);
        cout << "You entered: " << str;
        cout <<str + str;
    } while (str != "0");
}

How do I get the average of the numbers with only one variable and how do I get the biggest and smallest number?

Answer 1

you will have to define couple of other variables to track the smallest and largest values. you have to check whether a new number entered by the user is small than the earlier smallest value and whether the new number is larger than the earlier largest value.
