It serves to send usually text-based information on the monitor (in currently running application, window), for instance:
...
int myVariable;
cout >> "Please enter a number: ";
cin >> myVarible;
//You entered number 5
cout << "You entered the number: " << myVariable;
...
In the application window you will see:
Please enter a number:
5
You entered the number: 5

What is the definition of cout?
COUT is an inbuilt function in c++ language. Cout is used to print something on to the standard output.
What does code is case-sensitive mean when it is all numerical?
It means that you are writing code computer generates different names for x and X, also it will understand commands or will not under stand it at all (c++: cout and Cout are different).

What is c out?
most basicaly if I tell, cout is the printing statement in c++. cout<<"Hello world"; The above statement will print the sentence "hello wold". with the expression cout <<variable, the contents of variable is printed to the standard output. int variable=10; cout<<variable; The o/p will be 10..... Hope this will help u.... :)
