Actually the C programming language has no input or output operations defined as part of the language, they must be user defined. Since everybody does not want to reinvent his own input and output operations, the compiler writers have done a lot of this for us and supplied us with several input functions and several output functions to aid in our program development. The functions have become a standard, and you will find the same functions available in nearly every compiler.
You should print out the file named "stdio.h" and spend some time studying it. There will be a lot that you will not understand about it, but parts of it will look familiar. The name "stdio.h" is sort of cryptic for "standard input/output header", because that is exactly what it does. It defines the standard input and output functions in the form of #defines and macros. Don’t worry too much about the details of this now. You can always return to this topic later for more study if it interests you, but you will really have no need to completely understand the "stdio.h" file. You will have a tremendous need to use it however, so these comments on its use and purpose
are necessary.
