Question

Write a program in C++(no import of Javax or anything similar) that does the following:

There is a class human and a derived class student.
The enum in this case is gender(male, female)

Read in a text file of unknown line number that is formatted:
name;id;enum
name1;id1;enum1

The delimiter is ';'
Dynamically allocate student objects and store the objects in the array humanList (an array of human pointers). Include a counter for number of lines in the file as well.

Answer 1

#include <iostream>
#include <fstream>
#include <string.h>

using namespace std;
class human{
  
};
class student : public human{
    public:
        char name[10];
        int id;
        char gender[4];
};
int main()
{
   student *s = new student; //dynamic allocation to student object;
   human *h[2]; //an array of human pointers
   int j,k, i;
   char line[64]; char words[3][10];
   int count = 0, l = 0;
   ifstream file("data.txt"); //open the input file
   j = k = 0;
   while(file >> line) // reading file line by line
   {
       count++;
       for(i=0; i<strlen(line); i++){   //separate the words by ;
           if(line[i] == ';'){
             
               words[j][k] = '\0';
               j++;
               k=0;
           }
            else
               words[j][k++] = line[i];
        }
         strcpy(s->name,words[0]);
         s->id = atoi(words[1]);
         strcpy(s->gender, words[2]);
         cout<<s->name<<" "<<s->id<<" "<<s->gender<<"\n";
         h[l++] = s; // store the student object to an array of human pointers
         j = 0;
        }
         cout<<"Number of Lines: "<<count<<"\n";
        return 0;
}
