Variable number of parameters in function in C++

Question

How I can have variable number of parameters in my function in C++.

Analog in C#:

    for (int i = 0; i < a.Leng         


        

Answer 1

In C++11 and later you can also use initializer lists.

int sum(const initializer_list &il)
{
    int nSum = 0;
    for (auto x: il) 
        nSum += x;
    return nsum;
}

cout << sum( { 3, 4, 6, 9 } );
