如何使用 std::format 打印容器的内容

Question

Using fmtlib , we can print a container as follows:

#include <vector>
#include <fmt/ranges.h>

int main() {
  std::vector<int> v = {1, 2, 3};
  fmt::print("{}\n", v);
}

Can I do the same in the c++20 standard library version?

Answer 1

Formatting ranges is not a part of C++20 std::format but P2286 proposes it for C++23.
