signal 10 error

[Fox101]

Useing Xcode I keep getting an error for executable runner: program has exited due to signal 10(SIGBUS).

This happens anytime I try to input a choice from the menu, so I dont think the code is running the switch statement correctly but I cant find anything wrong with it. Any help would be greatly appreciated.

#include <stdio.h>

int main (void)
{/*main*/
	int avg, choice=1, num, sum=0, i, num_max=0;
	
	
	while(choice>=1 && choice<=5)
	{/* while */
	
	printf("Please choose one of the following\n");
	printf("1. Find the average\n");
	printf("2. Find the largest\n");
	printf("3. Exit\n");
	scanf("%d", choice);
	
	
		switch(choice)
		{/*switch*/
			case 1:/*find average */
				i=0;
				while(i<10)
				{/*while*/
					printf("Enter number:");
					scanf("%d",num);
					sum=sum+num;
					i=i+1;
				}/*while close*/
				avg=sum/10;
				printf("The average of the numbers is: %d\n", avg);
				break;
			case 2: /*find max*/
				i=0;
				while(i<10)
				{/*while*/
					printf("Enter number:");
					scanf("%d",num);
					if(num>num_max)
					num_max=num;
					i=i+1;
				}/*while close*/
				printf("The largest value is: %d\n", num_max);
				break;
			case 3:
				printf("Exiting");
				break;
			default:
				printf("Error");
				break;
		}/*end switch*/
	}/*end while*/
	
return(0);
}/*end main*/

scanf("%d", choice);

This is incorrect. You need to pass an adress to scanf. This is correct

scanf("%d", &choice);

Wow, I feel dumb now. Thanks.

Everyone did those kind of errors, don't worry. You learn that way.
