Question

Write in C++ program

Larger than n

In a program, write a function that accepts three arguments: an array, the size of the array, and a number n. Assume the array contains integers. The function should display all of the numbers in the array that are greater than the number n.

Input from the keyboard: The filename and path of a list of integer numbers.

                                          The number n to test the file numbers.

Output to the console: The numbers in the array that are greater than the input number n. (A title and your name should be on the output.)

Assumptions: The list of numbers input from the file will not contain more than 50 integers.

Sample file: hw7File.txt

Sample console output:

      HOMEWORK #7

Enter the filename with the list of numbers G:hw7File.txt

Enter the integer to test integers greater than: 5

The numbers in the list that are greater than 5 are:

#include<iostream>

#include<fstream>

using namespace std;

void fxn(int arr[], int size, int n)

{

    int i;

   

    // traverse the array

    for( i = 0 ; i < size ; i++ )

    {

        // if the current element is greater than n

        if( arr[i] > n )

            cout<<arr[i]<<endl;

    }

}

int main()

{

    string filename;

    int n;

   

    cout<<"      HOMEWORK #7\n";

    cout<<"Enter the filename with the list of numbers : ";

   

    // get user input

    cin>>filename;

   

    cout<<"Enter the integer to test integers greater than: ";

   

    // get user input

    cin>>n;

   

    // open file in read mode

    ifstream in(filename.c_str());

   

    int arr[100000];

    int size = 0;

   

    // loop untill file is completely traversed

    while( !in.eof() )

    {

        int x;

       

        // read from file

        in>>x;

       

        arr[size++] = x;

    }

   

    cout<<"The numbers in the list that are greater than 5 are:\n";

   

    fxn(arr, size, n);

   

    return 0;
