   FILE *fptr;
   char fname[20]="test.txt";

    printf("\n\n Create a file (test.txt) and input text :\n");
	printf("----------------------------------------------\n"); 
   fptr=fopen(fname,"w");	
   if(fptr==NULL)
   {
      printf(" Error in opening file!");
      exit(1);
   }
   printf(" Input a sentence for the file : ");
   fgets(str, sizeof str, stdin);
