What are the function of c plus plus language?

Answer 1

C++ is merely a tool, it has no specific role in mathematics other than to compute complex mathematical algorithms much faster and more accurately than any human could. But that is more specifically the role of the computer itself: C++ merely makes it possible to program the necessary machine code than would otherwise be possible with low-level assembly, using abstract objects that emulate real-world object behaviours.

Answer 2

Functions allow you to reuse code in your program instead of having to copy and paste the same code in different places. Here is an example of a function:

void myFunction()

{

cout << "This is a function." << endl;

}

The example above declares a function named myFunction() with a return type of void, which means it doesn't return anything. The function, once called, outputs the words "This is a function" onto the screen.

You can also supply arguments to functions, which allows a two-way communication line between the caller and the function. An argument is a variable that is passed to the function when it is called.

Here is another example:

int myFunction(int number, int number2)

{

cout << "Result: " << number + number2 << endl;

}

The above example function is able to carry two arguments, number and number2. When the function is called, it adds the two variables together and outputs the result.

You call a function as follows:

(return type) functionName(any arguments);
