Thread: Program crashes when a loop is meant to begin

The way to delete a record is --- well actually -- you don't wanna delete it.

As it turns out, it's great having some deleted records in your database. Because that's where you will stick in new records, without having to shift all the rest around, as much.

For a deleted record, just remove the primary key - whether it's an ID number set to zero, or whatever. Also, put an end of string char as the first char in the name field:

Smith, becomes \0mith. Now you have these deleted records in your data file, so you set your printing function not to print empty records:

Code:

for(i = 0; i < MaxNumber; i++) {
  if(ID) {
     printf("\n Name: %s   ID: %d  Phone Number: %s", recs[i].name, recs[i].ID, recs[i].phone);
  }
}

When you need to add a record, you just have your add function locate an already empty slot:

Code:

for(i = 0; i < MaxNumber; i++)  {
   if(ID == 0) {
      //found one that's empty, add the record data code right here
   }
}

What have we accomplished with this? We just shift our records around, a lot less. Make a few adjustments to our code, and we're good to go. It's easy enough to shift records, but when you have a large number of records, it's just not what you want to waste computer time, doing.

Thank you, Adam!

The help I have received from this forum is amazing. Can I ask everyone your motivation for helping people on here? Is it purely out of satisfaction from helping people?

Oh no!

I have your address now, from my high-tech sleuthing program. You can expect a large bill at the end of the month.

Lol it's okay. Have everything. It's not mine!

So while I would like to pretend to be an altruist because I answer way more questions than I ask, this is not totally true; I tend to benefit in the process too. However, I do think forums are one of the best programming resources you could possibly desire. Nothing beats a good forum (or mail list, but they are slower) when you are up some strange creek and have never heard of a "paddle". Also, you are in close communication with other programmers. Hence, I'm happy to try and make that possible on whatever level I can. There's a lot to learned from just reading some threads, and you can't leave it up to the same three or four people to write all of them.

This seems like a really good idea for learning programming and you help others in the process. Maybe I'll do that when I have time to learn it properly lol.

I haven't had time to learn to code from the beginning, which I why I'm struggeling so much! But in the holidays, there will be
