Which error are you likely to get when you run the following

Which error are you likely to get when you run the following program in TC/TC++?

#include <stdio.h>
int main ( )
{
     struct emp
      {
        char name[20];
        float sal;
      };
     struct emp e[10];
     int i ;
     for (i = 0; i <= 9; i++)
     {
        printf ("Enter name and salary : ");
        scanf ("%s %f" , e[ i ].name, &e[ i ].sal);
     }
    return 0 ;
}

1. Suspicious pointer conversion
2. Floating point formats not linked
3. Cannot use scanf ( ) for structures
4. Strings cannot be nested inside structures

Correct Option: B

Floating point formats not linked

Just add the following function in your program. It will force the compiler to include required libraries for handling floating point linkages.

static void force_fpf() /* A dummy function */
  {
    float x, *y; /* Just declares two variables */
    y = &x;      /* Forces linkage of FP formats */
    x = *y;      /* Suppress warning message about x */
 }
