Hi guys ! I've made a program that marks a seat taken X in an airplane ..
So, here's what I've done.. it runs , but when i try to input other seat code, i.e., 1G, the no.2 in the grid becomes 88.. and I don't know how did that happen and how to fix it.. Please help me . Thanks . :)

#include <stdio.h>
#include <conio.h>

   int x, y ;
   char s, z=1;

 struct grid {

      char upuan[5][5];
  }seats;

 void main(){

 clrscr();
 void GRID();
 void SEAT();

 GRID();
 SEAT();


  getch();}


  void SEAT(){
   int v;
   char chose[3];
   void display();
   printf("\n\nWhat seat?:\t");
   scanf("%s", chose);

   switch (chose[0]) {
      case '1': x=0;  break;
      case '2': x=1;  break;
      case '3': x=2;  break;
      case '4': x=3;  break;
      case '5': x=4;  break;
      case '6':break;
      case '7':break;

   }
   switch (chose[1]){
      case 'a':break;
      case 'A': y=1;  break;

if  (seats.upuan[x][y]!='X')
	    { seats.upuan[x][y]='X';

	     SEAT(); }
     display();

	printf("\n\nWould you like to select again? 1-yes 0-no ");
 scanf("%d", &v);
   if (v==1)
    SEAT();



	}



  void GRID() {
 int col=27;
 int row=2;
   for(x=0; x<=4; x++){
     s='A';
     for (y=0,col=27; y<=4; y++){
       if (y==0){
	 seats.upuan[x][y]=z;
	 gotoxy(col,row);
	 printf("%d\t", seats.upuan[x][y]);

	 }
       else {
	 seats.upuan[x][y]=s;
	  gotoxy(col,row);
	  printf("%c\t", seats.upuan[x][y]);
	  s++; }
	  col+=5;
	  }

     z++; }   }


void display()

   clrscr();

Ah .. I just missed to put default .. My problem is solved already .. :)

plz mark the thread as solved:)

If you started the thread, there should be a "Mark as Solved" link below the last post.
