the source file is just an ASCII file, (i can be non ASCII one but most of the case it is ) , wish the compiler reads and compile, assemble to the machine language , the header file is a file will allow you to include it in your sources , just like for example the math libraries ,in order to use them you have to do #include<math.h> then the compiler will look for the math libraries and include the necessary functions , you can also produce your own header file in your project , i mean not all the programs has to be written in the same source file, since you can define your objects/methods/ ..... in another sources and link them if needed .

if this is not that helpful post here or just use wikipedia .

Regards.
