Console Output (cout)

Console Input (cin)

Another statement defined in the C++ libarary called iostream is cin.  This is used to ask the user for a value of a variable.

Example

int Age;

This is a way for the declaration of variables.  More on data types and declaration of variables will be discussed on the next lesson.

<<endl;

This has the same function with \n but instead, this is placed outside a quotation marks.

cin>>Age;

This statement would have the program ask for a value for the variable Age.

cout<<Age;

This statement asks the program to display the value for the variable Age.
