Function calling is where your code branches off to execute a function and then returns to the instruction following the call. The function may also return a value that can be stored and/or processed by the code that called it. Functions allow common code to be separated from the code that uses the common code, thus reducing maintenance (the code in the function is written once, rather than every time it is required).

test(1, 2, 3);
Another example is if I want to use an object's function. If I have an object named testObject which has a function testFunction, I can do:
testObject.testFunction();
If I have a pointer testPointer pointing to testObject, I can do:
testPointer->testFunction();

What is a reference variable in c plus plus?
A reference variable in C++ is a formal parameter of a function call that automatically dereferences itself, as if it were a pointer, into a reference to the original value in the calling routine. You declare the reference type in the function declaration and prototype, but the compiler automatically adds the reference (&) operator on call, and the dereference (*) operator on use.
