Whats wrong with my template function, its giving me me the error of no known conversion?


This Content is from Stack Overflow. Question asked by Matthew Joel

So here is my template, which has a findMax function in order to find the largest rectangle object in a vector:

    template<typename Object, typename Comparator> 
const Object & findMax(const std::vector<Object> & rectangles, 
Comparator cmp) { 
   int MAX = 0; 
   for(int i = 1; i < rectangles.size(); i++) { 
      if(cmp(rectangles[MAX], rectangles[i])) { 
         MAX = i; 
   return rectangles[MAX]; 

and here is the the line of code where the error occurs:


My display function works, and now im simply trying to display the rectangle is finds largest, but i get the error:

 candidate function not viable: no known conversion from 'const Rectangle' to 'std::vector::size_type

Im stumped, what should i try?
