The language is C

Sorry this question has a lot of text but most of it is just defining things and stuff I made to help for testing the code

//I have included a main function to help with testing (You do not have to add anything else to it but if it helps you with testing you are welcome to add) :)

You can NOT include any other c libraries and can NOT use any built in functions other than ones that can examine strings such as strcpy() and strcmp()
