    If you're using gets, you've already lost. In this case, not only are you using gets, but you are using it incorrectly (the parameter passed to it is supposed to be a char*, not an int, and surely needs to point at actual memory (hint: 00 is not actual memory)).

    EDIT: I suppose I should be very clear about this: take any use of gets right out of your program. You can use fgets, or scanf, as you wish.

    Code:
       int SearchName = 00;
       gets(SearchName);
    basically reads in data from the user and writes it - using the unsafest function you could have found for reading a string, gets() - to a NULL pointer. That is a crash waiting to happen.

    If you are getting complaints from your compiler, address them first. But, basically, in current form, your code is rubbish.
    Right 98% of the time, and don't care about the other 3%.

    fgets takes more arguments than gets. Try google.

    Hi Bob... Mind if I chip in just a little bit of advice here?

    In your place I would post the problem code, clearly highlighting the parts that are producing errors, and explaining what you've already done to try and fix it...

    The hassle you're getting seems more related to how you are asking the question than anything else... (loony BASIC examples, aside).

    Before he edited the original post to remove the code, that code contained no variable named c, initialised or not. It therefore had absolutely no relevance to the problem described.

    When someone can't be bothered applying the effort to ask a meaningful question, they tend to get static.
