Thread: Switch Problem

Code:

#include <stdio.h>

char option;

void PURCHASE(), VIEW(), QUIT();
void BUSINESS(), ECONOMY();

void main(){
	printf("AIRLINE RESERVATION SYSTEM \n");
	printf("P - to Purchase Ticket \n");
	printf("V - to View Arrangement \n");
	printf("Q - to Quit the system \n");
	printf("Enter the option : ");
	scanf_s("%c", &option);
	getchar();

	switch(option){
		case '1':
		case 'P':
		case 'p':
			printf("Purchase\n");
			//PURCHASE();
			break;

		case '2':
		case 'V':
		case 'v':
			printf("View\n");
			//VIEW();
			break;

		case '3':
		case 'Q':
		case 'q':
			printf("Quit\n");
			//QUIT();
			break;

		default:
			printf("Invalid Option \n");
			break;
	}
}

Please help me see what is the problem, no matter that character or number I entered, the program also display Invalid Option.
