I seriously have no clue why it isn't working, it compiles but no luck getting any of the options to work besides input entry any suggestions will be so greatful!

>>line 38: return main();

Never ever under no circumstances should you make recursive calls to main(). That function is to be called only by the operating system during the program's initial startup. When you want to repeat something, like that menu, use a do or while loop.

I've gotten rid of the recursive calls to main and edited the methods with delete, search and enter info to return to main after they've finished their use.
Your more than welcome to run the code in a compiler yourself because from what I've learnt I don't know why it won't recognise the entries I enter for the search and delete method.

scanf() is an evil function because it may not process all the keys in the input keyboard buffer(). It can not be used to get strings that contain spaces, such as most addresses, because "%s" stops at the first space. Replace all instances of scanf() with fgets(). For integer input, e.g. "%d" or "%i", use fgets() with character buffer then convert it to integer.

I've now got both the search and delete functions working but now I need to specify which entries to delete, right now it displays entries I've just entered, and deletes them when I ask it to but if I put in more than one I don't know how to specify the entries I wish to delete any suggestions?
