C++ please. How can I implement the function definition (where the comment block on definitions. cpp is)? I am using a three file format and have attached the three files (definitons. cpp, header. h, main. cpp). The definitons. cpp file is the ONLY file that needs modification.

DEFINITIONS. CPP

#include "header. h"

* Function: importPackagesLog ()
* Date Created: 11/27/20
* Date Last Modified: 11/27/20
* Description: This function reads a data set from an input file
* and stores each line of package data in a
* corresponding vector
* Input parameters: output parameter variables for names, sizes,
* and weights of packages
* Returns: N/A
* Pre: The input file contains a list name and one or more sets of
* package data consisting of recipient name, package size,
* and package weight
* Post: Each package data from the input file is now stored in a
* set of parallel vectors

/
* Function: printPackageList ()
* Date Created: 11/27/20
* Date Last Modified: 11/27/20
* Description: This prints the contents of the package list read
* from file
* Input parameters: package list name, a vector of names, sizes,
* and weights of packages
* Returns: true if package list name is not an empty string and
* all vectors are the same size
* Pre: The input string and vectors are not empty (at least one
* item read from the input file)
* Post: Each package data is printed to the console output
