IIRC, importing an entire namespace into scope is a feature that was added exclusively for backwards compatibility and is not idiomatic modern C++.
What is idiomatic is explicitly importing individual symbols into a name peace.
#include <iostream>
#include <vector>
#include <string>
using std::cout;
using std::vector;
using std::string;
int main() {
vector<string> v {"explicit ", "is better ", "than implicit\n" };
for (auto p: v) cout << p;
return 0;
}
I'm on mobile so please forgive errors.
- 2bitencryption 11y agoWow, I never knew about that. I always hated having std:: everywhere, just so I could have "correct" C++. But I also hated referencing to std implicitly. This is the perfect tradeoff: explicitly state intentions in the beginning, then implicitly reference them as you go. (works until you use eighty five billion lines just to import your symbols)
