How can a for loop count input?

Question

C++ / C#

#include <iostream>

int main()
{
    int sum = 0;

    // Разрешаем пользователю ввести до 10 чисел
    for (int count=0; count < 10; ++count)
    {
        std::cout << "Enter a number to add, or 0 to exit: ";
        int val;
        std::cin >> val;

        // Выходим из цикла, если пользователь введет 0
        if (val == 0)
            break;

        // В противном случае, добавляем число к общей сумме
        sum += val;
    }

    std::cout << "The sum of all the numbers you entered is " << sum << "\n";

    return 0;
}

How can the for loop read how many times I entered characters and if this number reaches 10, then the program ends, we did not select anything. Please explain

Answer 1

You have a loop of 10 iterations ( for (int count=0; count < 10; ++count)). With a possible early exit ( break).
