What is int k{1}; in c++ ?

Answer 1

That is a new way to initialize variables in C++11.

Answer 2

In C++11 you can use int k{}; instead of int k = 0;.
int k{}; may not work unless C++11 standard is enabled.

Answer 3

It would. The example in my lessons is
vector<int> number {6, 5, 4, 3};
cout << number [2];
I'm not sure on the array initialization. I don't have C++11 on my mobile to test it.

Answer 4

It is equivalent to "int k = 1;" in this context.

Answer 5

thanks for the explanation guys :)
