Question

Please solve questions in C++ ASAP!! thank you

(a) Write a function in C++ called readNumbers() to read data into an array from a file. Function should have the following parameters:

(1) a reference to an ifstream object
(2) the number of rows in the file
(3) a pointer to an array of integers

The function returns the number of values read into the array. It stops reading if it encounters a negative number or if the number of rows is exceeded.

(b) Write a program with the main() function is designed to use the readNumbers() function from the previous part of this question to read the data from a file called inputData.txt to the array.

FUNCTION readNumbers() and C++ CODE with ifstream() as refrence :

//C++ CODE reads data from a text file into an array.

#include <bits/stdc++.h>
#include <fstream>
using namespace std;

//To store elements 
vector<int> numbers;


//Function to read Array from file
void readNumbers(ifstream& inputFile){

    // Check if exists and then open the file.
    if (inputFile.good()) {
        
        // Push items into a vector
        int current_number = 0;
        //Checking if number in file is positive and number exist
        while (inputFile >> current_number and current_number>=0){
            numbers.push_back(current_number);
        }

        // Close the file.
        inputFile.close();

        // Display the count of numbers read.
        cout << "The count of numbers are: ";
        cout<<numbers.size();
        cout << endl;
    }else {
        cout << "Error!"; //If error occurs or file is missing.
    }
}

int main()
{
        ifstream inputFile("inputData.txt");
    readNumbers(inputFile);
    return 0;
}

INPUT FILE :

OUTPUT :
