Please help me write a constructor in a separate LargestK.cpp file..I have written have included LargestK01.h and maindriver.cpp file.
I have written a program that gets a file name and number of largest entries from the keyboard, then reads the file and reports the largest entries. The program uses the LargestK class and I have written a declaration of that class. Your job is to determine any additional private data members for the LargestK class and write the definitions of a constructor and several methods for the class.
// LargestK01.h
// Declare the LargestK class.
// A LargestK object tracks the k largest doubles sent to
// it.
#ifndef _LARGEST_K_H_
#define _LARGEST_K_H_
#include <vector>
using std::vector;
class LargestK
{
public:
// constructors
// post: this LargestK object is tracking the k largest
// entries sent, via calls to putEntry, by the
// client code. No entries have been sent yet.
explicit LargestK( size_t k );
// mutators
// post: x has been added to the sequence of entries
// processed by this LargestK object.
void putEntry( double x );
// accessors
// post: The number of largest entries tracked by this
// LargestK object has been returned.
size_t getK() const;
// post: The number of entries sent to this LargestK
// object has been returned.
size_t getEntryCount() const;
// pre: 0 <= i < getK() and i < getEntryCount().
// post: The ith largest entry sent to this LargestK
// object has been returned ( i=0 for largest,
// i=1 for next largest, etc. ).
double getLargest( size_t i ) const;
private:
size_t k_;
vector<double> largest_;
};
#endif
// largestKDriver01.cpp
// Get k and file name from keyboard.
// Read file and report k largest doubles.
