How to make std::vector work in gcc?

Question

C++ / C#

Good afternoon, the simplest code with std::vector in gcc does not work.

#include <vector>

using namespace std;

int main(int argc, char const *argv[]) {
  vector<int> tmpvector;
  tmpvector.reserve(10);
  return 0;
}

Error output:

Answer 1

What language is selected in Xcode for the project? There is no gcc on macOS, only an alias, which is actually clang. Try compiling in a terminal with clang or g++.
