When I made a separate class file in code blocks and compiled it. Code blocks gived a fatal error of 'No such file or directory' and had the address of the project. I have re checked every thing but there is no problem in codes or in anything else. I have made the class using the class wizard in code blocks and also checked the box saying to keep header and source file in same directory and they are in same directory. Please tell me any suggestion on solving this problem.

I don't understand clearly what is the difference between compiled and interpreted? As they all are translated to another language when they are build.

The information on google is all about how to make them, But I want the mathematics needed for it and there's no clear answer i got on google for that reason.

You're(Leon de Boer) extremely right at the answer. Well I am not discriminating any programming language and I also believe that every programming language has its own power and uses. I also decided to learn C cause I want to be a system programmer as Java is not suitable for many low level services but C/C++ are one that has the pride.

Can anyone say which subjects and chapters in mathematics I need to know (thorough or basic) for learning algorithms? Also help me find a book on this mathematical subjects and a good book on algorithms for beginner?

Many people are stating that let us c is old and hard but when I read it there was no problem rather than the ide(but I am already known how to use a ide, Code::Blocks) and it was also the one book from which I get the idea of the technical things cause it is easy to understand. So what I do change it and go to a new book or remain firm on it?
