Question

Develop a C++ program that looks for a given value in a text file full of integer values

Prompt the user for a value to search for in the file

• No input validation is required

Open the accompanying text file named numbers.txt

Search the contents of the text file

• You may not "hard-code" the quantity of values found in the file...
• Use a loop of some sort until the end of the text file is reached

Maintain how many many times the value is found in the file

Close the text file when processing is complete

Display the number of times the value is found in the file

Number.txt

Answer 1

CODE -

#include<bits/stdc++.h>

// #include <iostream>

// #include <iomanip>

// #include <fstream>

// If you don't want to use <bits/stdc++> or your compiler doesn't support it, you can remove it and uncomment the above three header files for your code to work.

using namespace std;

main()

{

    int num,count=0;

    ifstream infile ("numbers.txt");

    if (!infile)

    {

        cout << "File not Found" << endl;

        exit(0);

    }

    cout << "Enter the number you want to search: ";

    cin >> num;

    int number;

    while(!infile.eof())            // loop will run until end of file.

    {

        infile >> number;           // getting number from the file.

        if (number == num)

            count++;                 // incrementing the count if number from the file matches the number to be searched.

    }

    infile.close();

    cout << count;

}
