 You should probably know at least the completely basic ideas of programming before reading this (what's a [programming language](programming_language.md), [source code](source_code.md), [command line](cli.md) etc.). If you're as far as already knowing another language, this should be pretty easy to understand.

 Optionally there may be an *else* branch which is gets executed only if the condition does NOT hold. It is denoted with the `else` keyword which is again followed by a command or a block of multiple commands. Branching may also be nested, i.e. branches may be inside other branches. For example:

 The file mode is now `"rb"` (read binary). For reading from binary files we use the `fread` function, similarly to how we used `fscanf` for reading from a text file. `fread` has these parameters: pointer where to store the read data (the memory must have sufficient space allocated!), size of one data item, number of items to read and the pointer to the file which to read from. As the first argument we pass `&byte`, i.e. the address of the variable `byte`, next 1 (we want to read a single byte whose size in bytes is 1), 1 (we want to read one byte) and the file pointer. `fread` returns the number of items read, so the `while` condition holds as long as `fread` reads bytes; once we reach end of file, `fread` can no longer read anything and returns 0 (which in C is interpreted as a false value) and the loop ends. Again, we must close the file at the end.

 We haven't covered the whole of C, not even close, but you should have pretty solid basics now. Now you just have to go and write a lot of C programs, that's the only way to truly master C. WARNING: Do not start with an ambitious project such as a 3D game. You won't make it and you'll get demotivated. Start very simple (a Tetris clone perhaps?).
