Question

.Using OOP, write a C++ program that will read in a file of names. The file is called Names.txt and should be located in the current directory of your program. Read in and store the names into an array of 30 names. Sort the array using the selection sort or the bubblesort code found in your textbook. List the roster of students in ascending alphabetical order. Projects using global variables or not using a class and object will result in a grade submission of 0. The Names used for the Names.txt are: Jackie, Sam, Bill, Tom, Mary, Paul, Zev, Barb, John, Sharon, Dana, Dominic, Steven, Padro,,Katey, Kathy, Darius, Angela, Mimi,Jesse Kenny, Lynn, Hector, Brittany, Jenn, Joe, Chloe, Geena, Sylvia, Dean. I tried this solution on this question and it had a lot of errors. I checked each solution in Microsoft Visual Studio and none runs properly. They have errors even though im told they run properly. When I run these solutions, I do not see a output visible. THis project is due tomorrow.

Answer 1

#include <iostream>

#include <fstream>

using namespace std;

void sort(string values[], int numValues){

    int i, j;

    string temp;

    // outer loop to travel through the all elements

    for (i = 0; i < numValues - 1; i++) {

      // inner loop to compare the outer loop elements

      

      for (j = 0; j < numValues - i - 1; j++)

        // if element at j< than j+1 than swap both

        if (values[j].compare(values[j + 1])>0) {

          // swap logic

          temp = values[j];

          values[j] = values[j+1];

          values[j+1] = temp;

        }

    

    }

    

  }

int main()

{

fstream inputFile;

int count;

string name;

count = 0;

string arr[30];

inputFile.open("Names.txt");

if (inputFile.fail()){

cout << "File open error....";

}

else{

while (!inputFile.eof()){

inputFile >> name;

arr[count]=name.substr(0,name.length()-1);

count++;

}

inputFile.close();

sort(arr,count);

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

cout<<arr[i]<<endl;

}

return 0;

}
