Question

//This program is your final exam.

//Please fill in the functions at the bottom of the file. (evenCount and insertItem)

//DO NOT CHANGE ANYTHING ELSE.

//main has all the code needed to test your functions. Once your functions are written, please build and make sure it works fine

//Note that in this case, the list is not sorted and does not need to be. Your goal is to insert the number in the given position.

#include <iostream>

#include <fstream>

using namespace std;

//constants

const int CAP = 100;

//function prototypes

bool openFile(ifstream &);

void readData(ifstream &, int [], int &);

void printData(const int [], int);

void evenCount(const int[], int);

void insertItem(int[], int &, int, int);

int main()

{

ifstream inFile;

int list[CAP], size = 0;

if (!openFile(inFile))

{

cout << "Program terminating!! File not found!" << endl;

return -1;

}

//read the data from the file

readData(inFile, list, size);

inFile.close();

cout << "Data in file:" << endl;

printData(list, size);

//insert a few items

insertItem(list, size, 15, 5);

cout << "Inserted in position 5:" << endl;

printData(list, size);

insertItem(list, size, 101, 2);

cout << "Inserted in position 2:" << endl;

printData(list, size);

insertItem(list, size, 215, 12);

cout << "Inserted in position 12:" << endl;

printData(list, size);

//call the evenCount function

evenCount(list, size);

//end program

cin.ignore(100, '\n');

cout << "Press any key to continue...";

getchar();

return 0;

}

//function to open file

bool openFile(ifstream &inFile)

{

inFile.open("numbers.txt");

if (!inFile)

{

return false;

}

return true;

}

//reads the data from the file

void readData(ifstream &inFile, int list[], int &size)

{

while (!inFile.eof())

{

inFile >> list[size++];

}

}

//print the contents of the array

void printData(const int list[], int size)

{

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

{

cout << list[i] << endl;

}

cout << endl;

}

//insert an item (newNum) in the given position (newPos)

void insertItem(int list[], int &size, int newNum, int newPos)

{

//insert code here

}

//count the even numbers in the list and output in this function

void evenCount(const int list[], int size)

{

//insert code here

}

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
