Python-like loop enumeration in C++ [duplicate]

Answer 1

One way is to wrap the loop in a function of your own.

#include 
#include 
#include 

template
void mapWithIndex(std::vector vec, F fun) {
   for(int i = 0; i < vec.size(); i++) 
       fun(vec[i], i); 
}

int main() {
   std::vector vec = {"hello", "cup", "of", "tea"};
   mapWithIndex(vec, [](std::string s, int i){
      std::cout << i << " " << s << '\n';
   } );
}
