Explanation / Answer

I have did it in C++

#include <iostream>
#define BUSY 1
#define EMPTY 0
/* run this program using the console pauser or add your own getch, system("pause") or input loop */
using namespace std;

int main(int argc, char** argv) {
   int arr[20],ticket;
  
   char ch;
   cout << " WELCOME TO THE BUS TICKET INFORMATION SYSTEM ";
   for(int i=0;i<20;i++)
       arr[i] = 0;
   do{
       cout << " A.Ticket Sale() B.Inquires() C.Report() D.get Out['s' for exit] Choose your option: ";
       cin >> ch;
       switch(ch){
           case 'A':
               cout << " Enter the seat you want: ";
               cin >> ticket;
               if(ticket >0 && ticket <=20){
                   for(int i=0;i<20;i++){
                       if(arr[ticket]==EMPTY){
                           arr[ticket] = BUSY;
                          
                       }
                   }
               }
               break;
           case 'B':cout << " Enter seat number: ";
                   cin >> ticket;
                   if(arr[ticket] == BUSY)
                       cout << " " <<ticket << " is OCCUPIED: ";
                   else
                       cout << " " << ticket << " is NOT OCCUPIED: ";
                  
                   break;
           case 'C':
               for(int i=0;i<20;i++){
                   if(arr[i] == BUSY)
                       cout << " " << i << " >>> BUSY ";
                   else
                       cout << " " <<i << " >>> EMPTY ";
                      
               }
               break;
           case 'D' : exit(0);
           default : cout << "Wrong Input ";
       }
   }while(true);
   return 0;
}
