Arrays

[yoda_21]

I having trouble with my program. Here is my code:

// Airlines Reservation system

#include <stdio.h>

main()
{

int business[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // declaring array
int economy[] = {11, 12, 13, 14, 15, 16, 17, 18, 19, 20}; // declaring array
int buscount = 0; // variable
int econocount = 0; // variable
int integer1; // variable

printf("Welcome to Sydney Airlines\n");
printf("Please choose 1 for business class or 2 for economy class or 3 to exit:"); //prompt
scanf("%d", &integer1); // reads the integer
printf("\n"); // inserts a new line
printf("\n"); // inserts a new line

// enter choice between business or economy class

// initializing business array

while(integer1 != 3) {
if(integer1 == 1){
if(buscount > 9){
printf("Switch to Economy");
break;

// Switches back to economy

econocount++;
printf("You are in seat %d, Economy", economy[econocount]);
printf("Would you like economy class? 1 = Y 2 = N:");
scanf("%d", &integer1);

} // this bracket belongs to the first if statement

printf("Welcome to Business Class\n");
buscount++;
printf("Your seat is %d", business[buscount-1]);

} // this bracket belongs to the second if statement

printf("\nEnter another? 1 = Y 2 = N\n");
scanf("%d", &integer1);


// this bracket belongs to the while loop



// initializing economy array

if(integer1 == 2){
if(econocount > 19){
printf("Switch to Bussiness");




// Swithches back to business

buscount++;
printf("You are in seat %d, Business", business[buscount]);
printf("Would you like economy class? 1 = Y 2 = N:");
scanf("%d", &integer1);

} // this bracket belongs to the first if statement

printf("Welcome to Economy Class\n");
econocount++;
printf("Your seat is %d", economy[econocount]);

} // this bracket belongs to the second if statement

printf("\nEnter another? 1 = Y 2 = N\n");
scanf("%d", &integer1);




// ends the program

if(integer1 == 3)
printf("Thank you for using the program\n");

} // this bracket is end the first while loop

return 0; // program excutes successfully
}





When I press 1 it goes through the business class until it gets to 10. Then the user gets a message if they want to switch to economy class. that works. But if I restart the program at economy class all I get is a message saying Enter 1 = Y 2 = N. What is wrong with the program. Can someone help me out plz

Umm... basically, you just have your while loop organized in such a strange way, problems like this are bound to come up. You need to redo it, using basically the following structure...

while(integer1 != 3)
{
 if(integer1 == 1)
 {
  // Handle business here.
 }
 else if (integer 1 == 2)
 {
  // Handle economy here.
 }
 printf("\nEnter another? 1 = Y 2 = N\n");
 scanf("%d", &integer1);
}
printf("Thank you for using the program\n");

Don't use any breaks for this program. They're unneccisary.
