file opening

[pinkpenguin]

i am writing a program that has the user input a file and then the file goes through two functions. I am having trouble opening the file. here is the code.

 
     printf("Enter the file to open: ");
     scanf("%s", &f);
     if((fp = fopen(f,"rt")) == NULL)
     {
       printf("NO SUCH FILE");
     }
     fgets(f, sizeof(f), stdin);
     fopen("fp", "r");
     while((fp = fopen(f,"rt")) == NULL)
     {
       fgets(f, sizeof(f), stdin);
       DI = dividing(com, one, two);
       FI =  performance( com, one, two);
     }
     fclose(fp);

fopen("fp", "r");

Huh?

[edit]A basic skeleton:

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

int main(void)
{
   char filename[FILENAME_MAX];
   FILE *file;
   fputs("filename? ", stdout);
   fflush(stdout);
   if ( fgets(filename, sizeof filename, stdin) != NULL )
   {
      char *newline = strchr(filename, '\n');
      if ( newline != NULL )
      {
         *newline = '\0';
      }
      file = fopen(filename, "r");
      if ( file != NULL )
      {
         /* ... */
         fclose(file);
      }
      else
      {
         perror(filename);
      }
   }
   return 0;
}
