Hi I am last year MCA student, currently I am learning C++ programming language.I want to know about max_element () function in C++. So please tell me how to use the max_element () function in the C++. All possible replies and suggestions on this topic are very much appreciated.

This function used to return iterator that shows element with max value in specific range. Max_element () function work shown as below:

Code:

template <class FrwrdItrtr>
  	FrwrdItrtr max_element ( FrwrdItrtr fst, FrwrdItrtr lst )
{
  		FrwrdItrtr lrgst = fst;
  		if (fst==lst) return lst;
  		while (++fst!=lst)
    		if (*lrgst<*fst)    
      		lrgst=fst;
  		return lrgst;
}

syntax of max_element() function:

Code:

template <class FrwrdItrtr>
  		FrwrdItrtr max_element ( FrwrdItrtr fst, FrwrdItrtr lst );
template <class FrwrdItrtr, class Cmpr>
 		 FrwrdItrtr max_element ( FrwrdItrtr fst, FrwrdItrtr lst, 
                                Compare cmp );
