AIM: Define an array which stores arr[]={11,22,33,44,55,66,77,88,99}. Write a program to illustrate the use of command line arguments that supplies the file name called ODD & EVEN to the program. Using command line arguments the odd numbers’ are stored into the ODD file & even numbers’ are stored into the EVEN file. Finally display the contents from both the files.

  

CODING:

#include<fstream.h>

#include<conio.h>

#include<iomanip.h>

#include<process.h>

 main(int argc,char *argv[])

{

int arr[9]={11,22,33,44,55,66,77,88,99};

if(argc!=3)

{

cout<<"parameter is not match:";

exit(1);

}

ofstream f1,f2;

f1.open(argv[1]);

if(f1.fail())

{

cout<<"error in opening file";

exit(1);

}

for(int i=0;i<=9;i++)

{

if(arr[i]%2==0)

{

f1<<arr[i];

}

f1.close();

f2.close();

ifstream fin;

char ch;

for(i=0;i<=argc;i++)

{

fin.open(argv[i]);

cout<<"content of file are";
