I just need the following cases only ! and I have added my code to save your time... so I just need few modifications

the following test cases will be due and must pass:

- Compile

- Count lines, words and characters in one file

- Correctly handle the file not found error case

- Detect poorly formed arguments

- Detect unrecognized arguments

My Code

-----------------------------

#include<iostream>
#include<string>
#include<fstream>
#include<cstring>
#include <iomanip>
using namespace std;

int main(int argc, char* argv[])
{
if (argc > 1)
{
}
else
{
cout << \"File anInvalidFileName is not found\" << endl;
return -1;
}
ifstream infile(argv[1]); //open the file
if (infile.is_open() && infile.good())
{
string line = \"\";
int countline = 0;
int charcount = 0;
char space;
int countspace = 0;
int empty = 0;
while (getline(infile, line))
{
if (line.empty())
{
empty++;
}
countline++;
charcount += line.length()+1;
for (int i = 0; i < line.length(); i++)
{
if (line[i] == \' \')
countspace++;
}
}
countspace = (countline-empty) + countspace ;
cout << setw (12) << countline ;
cout << setw(12) << countspace ;

This assignment involves writing a C++ program to identify and count lines, words, and characters. For the purpose of this assignment, we define a \"word\" as a sequence of characters that are not whitespace characters. Words are delimited by one or more whitespace characters. A whitespace character, such as a space, tab, or newline, is any character for which the

#includ<iostream>

#include<fstream>

#include<string>

#include<conio.h>

using namespace std;

int main()

string filename;

cout<<\"please enter the filename\";

cin>filename;

ifstream infile(filename,std::ifstream::in);

if(!infile)
