That is STANDARD input and STANDARD output.
By default, standard input is the keyboard, and standard output is the screen. Standard I/O is set by the operating system, though it may be redirected by script invocation or system commands within the C/C++ program itself. You could, for instance, set standard output to a printer or a file in lieu of a screen.
You should also Google Standard Error.
The <iostream> include file is a header file that contains the prototype declarations of functions that provide the basic input/output mechanisms in C++. The <iostream> header file sets up the objects that initialize the basic input/output pathways, cout and cin.
input is the << operator and output is the >> operator
If you know that the number input will always be three digits: output = 10 * (int)(input / 100) + (input % 10); If you want to idiot proof it (eg. too many digits): output = 10 * (int)((input % 1000) / 100) + (input % 10);

For basic input and output in C++: #include

scanf does not employ a delimiter. It simply reads formatted input from std::cin.
No. In C++ with <iostream>, cin is a prefedined class that represents stdin, so it is an input identifier.
I guess you mean either input/output/inout/append or binary/text.
There are two stream operators: << (insert or put) and >> (extract or get). Output streams implement the insertion operator, input streams implement the extraction operator and input/output streams implement both operators.
