Example: Enter a number: 3 Cube of entered number is: 27cube of 3 is (3*3*3) = 27.Time Complexity: O(1) In a pass by reference program, only basic input/output and swapping operations are performed, which takes O(1) time.
However, there is another way of passing arguments calledpass by reference. Pass by reference is a method of argument passing in functions where thereferencesof actual parameters are passed to the function, rather than their values. For example, ...

To modify a reference that is qualified by theconstqualifier, you must cast away its constness with theconst_castoperator. For example: #include <iostream> using namespace std; void f(const int& x) { int& y = const_cast<int&>(x); ...
10:00When you pass a variable by value,you can’t change its value in any meaningful way to be reflectedoutside of the calling environment.But when you pass a variable by reference,any change you make to that will have an effect after that function’s beencalled. In the next lesson,we...
, so they can't be used to return a value. They also can't return anything to the host through the standard C pass-by-reference. The reason for this is that addresses on the host are, in most systems, invalid on the device, and vice versa. For example, suppose we try something ...
You can modify your pass-by-reference C# example to illustrate this technique:C# using System; class Program { static void Main(string[] args) { int counter = 0; // Passing by reference. // The value of counter in Main is changed. Console.WriteLine(greet("Alice", ref counter)); ...
