   printf("Error opening file\n");  
        new_blk = (acc *)malloc(sizeof(acc));
        printf("\nEnter the name of person %d", i);
        scanf("%s",new_blk->name);                     //This part gets written correctly when i used only the name variable
        printf("\n Enter the current expenditure of %s", new_blk->name);
        scanf("%f",&new_blk->cur_exp);      // This section gives error
                                                                      // says scanf : floating point formats not linked
                                                                    //Abnormal program termination  
        fprintf(fp,"%s     %2f\n ",new_blk->name, new_blk->cur_exp);
        new_blk->next = NULL;
        if(*list_ptr == NULL)
         temp = new_blk;
         *list_ptr = temp;
         temp->next = new_blk;
         temp = temp->next;


It would be highly appreciable if someone could explain the meaning of the error message.

I don't get such an error when running this code. However, I did note (when I ran it) that you allocate memory for newblk in:

       new_blk = (acc *)malloc(sizeof(acc));
       printf("\nEnter the name of person %d", i);
       scanf("%s",new_blk->name);                     //This part gets written

but the name element of new_blk is merely: char *name.

Thus the scanf will be, at best, putting the name it reads into random memory, which could lead to all kinds of strange results past that statement.
You should allocate memory for name as well; something like:

       new_blk = (acc *)malloc(sizeof(acc));
       new_blk->name=(char *)malloc(30);  // allocate memory to name
       printf("\nEnter the name of person %d", i);
       scanf("%s",new_blk->name);                     //This part gets written

See if that helps the error you're getting as well, or not.
