Slip 3 - B) Write a C++ program to accept ‘n’ numbers from user through Command Line Argument. Store all Even and Odd numbers in file “Even.txt” and “Odd.txt” respectively.

 Solution:

#include <stdio.h>

#include <stdlib.h>

#include <istream>

#include <conio.h>

#include <ctype.h>

#include <fstream>

#include <iostream>

using namespace std;

int main(int argc, char *argv[])

{

    int num;

    ofstream f1("even.txt"),f2("odd.txt"); 

    if (argc == 1)

        printf("No command line arguments found.\n");

    else

    {

        for(int i = 1; i < argc; i++)

        {

            num = atoi(argv[i]);

            if(num%2==0)

            {

                f1<<num;

            }

            else

            {

                f2<<num;

            }

        }

    }

    return 0;

}
