Question

I know in C++11 they added the feature to initialize a variable to zero as such

double number = {}; // number = 0
int data{};  // data = 0

Is there a similar way to initialize a std::vector of a fixed length to all zero’s?

Answer 1

You don’t need initialization lists for that:

std::vector<int> vector1(length, 0);
std::vector<double> vector2(length, 0.0);
