Trouble copying a vector into a queue in c-CodePudding

I am working with a vector of around 400 float members and for my assignment I need to copy the vector into a queue. I never really understood the purpose of the queue and that has not made it easy. Here is what the function that I currently have....

template<typename T>
void vector_to_queue(std::queue<T> q, std::vector<T> v){
   for(vector<T>::iterator it = v.begin(); it != v.end(); it  ){
      q.push();
   }
}

This is as far as I've gotten, I am completely stumped and would appreciate any help that can be provided.

CodePudding user response：

You are pushing nothing to the queue, this should work for you:

template<typename T>
void vector_to_queue(std::queue<T>& q, const std::vector<T>& v){
   for(vector<T>::iterator it = v.begin(); it != v.end(); it  ){
      q.push(*it);
   }
}

CodePudding user response：

template<typename T>
void vector_to_queue(std::queue<T> &q, const std::vector<T> &v) {
   for (const auto &elem : v) {
      q.emplace(elem);
   }
}

Or little fancy

#include <algorithm>

template<typename T>
void vector_to_queue(std::queue<T> &q, const std::vector<T> &v) {
   std::for_each(v.begin(), v.end(), [&q](const auto &elem){ q.emplace(elem); });
}
