Question

my code deosn't run and it doesn't show any error. what's wrong about it !! it should loads data from a text file into an array of structs and prints the array to the screen

here is the code:

#include <iostream>
#include <string>
#include <fstream>

using namespace std;
struct Company {
   string Departmentname;
   int Departmentnum;
};
const int MAX = 20;

int main() {
ifstream File;
   Company arrayofdepartment[MAX];
   int Departmentcount ;  
   File.open("comapny.txt");
  
   if (File)
   {
      
       string theDepartmentname;
       int theDepartmentnum;
      
       Departmentcount = 0;

       while (File >> theDepartmentname >> theDepartmentnum)
       {
           if (Departmentcount < MAX)
           {
              
               arrayofdepartment[Departmentcount].Departmentname = theDepartmentname;
               arrayofdepartment[Departmentcount].Departmentnum = theDepartmentnum;

               Departmentcount++;
           }
           else
           {
               cout << "Capacity is reached. No more new student"
                   << " can be handled" << endl;
               break;
           }
       }
       for (int i = 0; i <Departmentcount; i++)
       {
           cout << arrayofdepartment[i].Departmentname << ",";
           cout << arrayofdepartment[i].Departmentnum << endl;

       }
   }
   else
   {
       cout << "Error opening the text file" << endl;
   }

return 0;                  
}

Code:

//include vector and sstream
#include <iostream>
#include <vector>
#include <string>
#include <sstream>
#include <fstream>

using namespace std;

struct Company {
   string Departmentname;
   int Departmentnum;
};
const int MAX = 20;

int main() {
ifstream File;
   Company arrayofdepartment[MAX];
   int Departmentcount ;
   File.open("company.txt");

   if (File)
   {
    
       string theDepartmentname;
       int theDepartmentnum;
       Departmentcount = 0;

       /*start of changes*/
       vector<string> v;
    
       //string to store current line.
       string temp;

       while (getline(File,temp))
       {
         
           std::stringstream ss(temp);
           std::string item;
           while (getline(ss, item, ','))
           {
            
              v.push_back(item);
           }
         
           //assigning splitted string to both the variables.
           theDepartmentname = v[0];
           //converting string to integer.
           stringstream s(v[1]);
           s>>theDepartmentnum;
           //cleaing the vector.
           v.clear();

           /*end of changes*/

           if (Departmentcount < MAX)
           {
            
               arrayofdepartment[Departmentcount].Departmentname = theDepartmentname;
               arrayofdepartment[Departmentcount].Departmentnum = theDepartmentnum;

               Departmentcount++;
           }
           else
           {
               cout << "Capacity is reached. No more new student"
                   << " can be handled" << endl;
               break;
           }
       }
       for (int i = 0; i <Departmentcount; i++)
       {
           cout << arrayofdepartment[i].Departmentname << ",";
           cout << arrayofdepartment[i].Departmentnum << endl;

       }
   }
   else
   {
       cout << "Error opening the text file" << endl;
   }

return 0;                
}
