Explanation / Answer

1.
User enters 1 :prints the LE
User enters 2 :prints the Unknown

2.
try
{

}
catch(domain_error& e)
{

}
catch(logic_error& e)
{

}
catch(exception& e )
{

}
exception is the base for all exceptions that is handeled at the last catch block

3.
a) #include"tools.h" and #include"core.h" should be included in the main.cpp file
b) core.cpp file should included #include"core.h"

4.
Function Declaration: .h
Class Definition : .h and .cpp
Method Definition: .cpp
Function Definition: .cpp

//5.
#include <iostream>
#include <fstream>

using namespace std;

int main()
{

int number_of_lines = 0;
string line;
ifstream myfile("wordfile.txt");
while (myfile.good ())
{
getline(myfile, line);

++number_of_lines;

}
cout << "Number of lines is "<<number_of_lines<< endl;
return 0;
}
wordfile.txt
word1
word2
word3
word4
word5

OUTPUT:

Number of lines is 5
