Is there a way to define variables of two different types in a for loop initializer?

Question

You can define 2 variables of the same type in a for loop:

int main() {
  for (int i = 0, j = 0; i < 10; i += 1, j = 2*i) {
    cout << j << e         


        

Answer 1

Well, it's ugly. But you could use pair.

int main() {
  for (std::pair<int,float> p(0,0.0f); 
       p.first < 10; 
       p.first += 1, p.second = 2*p.first) {
    cout << p.second << endl;
  }
}
