truncated loop

[CASHOUT]

The switch statement truncates due to the fact that a char variable is being associated with the integer variable choice. How can I fix the switch statement so that it recognizes the Q inputted by the user instead of truncating?
Can I scan for a integer or a char and place the value into integer choice?

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>



//function prototypes
void sumIntegers ();

void sumDoubles ();

void calcFactorial ();



int main()
{
	int choice = 0;
	/*char quit = 0;*/
	char Q = 0;
	

		printf("\t\tWelcome, please select from the following options.\n\n\n\n");

do
{
		
		printf("Please choose from the following options:\n\n\t1: Sum of even integers\n\n\t2: Sum of dollar amounts\n\n\t3: Factorial of a number\n\n\tQ: to quit\n\n\t:");
		
		
		scanf(" %d", &choice);
		/*scanf(" %c", &choice);		*/
	
	switch (choice)
	{
		
		case 1 :
			{
			sumIntegers ();
			break;
			}
		
		case 2 :
			{
			sumDoubles ();
			break;
			}
		
		case 3 :
			{
			calcFactorial ();
			break;
			}
		
		case 'Q' :
			{
			printf(" Have a nice day.\n\n");
			return 0;  // break
			}
		
		default :
			{
			printf("\n\n\n*** You entered an invalid choice!!! ***\n\n\n");
			}
	}	


	
}
while(choice != Q || choice > 3 || choice < 1);	// make sure to correct quit loop


	return 0;
}

Why does choice have to be an integer? Why not make choice a char and then make the switch/case like so:

switch(choice)
{
     case 'Q':
          ...
     break;

     case '1':
          ...
     break;
}

And so on?

Thanks Neo1 I'll give that a try

Neo1 Thanks again. The program runs great now. I appreciate you.
