passing structures

Hi!

I have a structure defined as follows:

Code:

---

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 :

Code:

---

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

Code:

---

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?

Code:

---

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

Code:

---

#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.
