You should really be more specific and not just throw down an entire program and say you want to someone to clean it up for you.
Thank being said I noticed right away you had a few improperly placed curly braces. Your very first if statement is missing an opening brace and further down you have an unnecessary opening brace after user=fopen("Username.txt", "r")
Beyond that indentation is completely off throughout and your switch statements make it really hard to follow what it is you're trying to accomplish with them.
My advice is to read through the compiler errors and locate each issue one by one, and if you're having a problem you can't solve then be specific and post the errors you're getting with your program.
