passing structures

[strokebow]

Hi!

I have a structure defined as follows:

struct	passenger
{
int flag;  //Use as a boolean - 1 if seat taken, 0 if not taken
char first[NAME];
char last[NAME];
};

typedef struct passenger pass;

And I pass it to a function to modify the contents - name and last :

void option_c(pass cust[][LABEL])
{	char ans[3], label;
	int row;

	printf("Enter the seat number you wish to edit: ");
	
	seat_check(&row, &label, ans);

	if (cust[row][label].flag)
		printf("blah blah balh");

	else
	{
                                printf("Enter first:");
		scanf("%[^\n]", cust[row][label].first);
		fflush(stdin);
                                printf("Enter second:");
		scanf("%[^\n]", cust[row][label].last);
		fflush(stdin);
                }
}

The problem lies in the else. For some unknown reason - the program will crash at this point

fflush(stdin);

*gasp*

Why fflush(stdin) is wrong

Where exactly does it crash? On the scanf()s? What are row and label set to by seat_check()? 12273849?

else
{
        printf("Enter first:");
        fgets(cust[row][label].first, NAME, stdin);
		/*scanf("%[^\n]", cust[row][label].first);
		fflush(stdin);*/
		
		
        printf("Enter second:");
		fgets(cust[row][label].first, NAME, stdin);
		/*scanf("%[^\n]", cust[row][label].last);
		fflush(stdin);*/

}

use fgets

Don't forget to remove the newline. From http://faq.cprogramming.com/cgi-bin/...&id=1043284385

#include <stdio.h> 
#include <string.h> 

int main()
{
  char buf[BUFSIZ];
  char *p;
  
  printf ("Please enter a line of text, max %d characters\n", sizeof(buf));
  
  if (fgets(buf, sizeof(buf), stdin) != NULL)
  {
    printf ("Thank you, you entered >%s<\n", buf);
    
    /*
     *  Now test for, and remove that newline character
     */
    if ((p = strchr(buf, '\n')) != NULL)
      *p = '\0';
      
    printf ("And now it's >%s<\n", buf);
  }
  
  return 0;
}


/*
 Program output:

Please enter a line of text, max 512 characters
this is a test
Thank you, you entered >this is a test
<
And now it's >this is a test<
*/

I seriously doubt that's the problem though. I bet the values of row or label are wacky.
