Day 21: Generics.cs

/*
Objective:
Today we're discussing Generics; be aware that not all languages support this construct, 
so fewer languages are enabled for this challenge. 
Check out the Tutorial tab for learning materials and an instructional video!

Task:
Write a single generic function named printArray; 
this function must take an array of generic elements as a parameter (the exception to this is C++, 
which takes a vector). The locked Solution class in your editor tests your function.

Note: You must use generics to solve this challenge. Do not write overloaded functions.

Input Format:
The locked Solution class in your editor will pass different types of arrays to your printArray function.

Constraints:
You must have exactly 1 function named printArray.

Output Format:
Your printArray function should print each element of its generic array parameter on a new line.

# Provided by HackerRank:
using System;

class Printer
{

	//
	*    Name: PrintArray
	*    Print each element of the generic array on a new line. Do not return anything.
	*    @param A generic array
	/
    // Write your code here


    static void Main(string[] args)
	{
		int n = Convert.ToInt32(Console.ReadLine());
		int[] intArray = new int[n];
		for (int i = 0; i < n; i++)
		{
			intArray[i] = Convert.ToInt32(Console.ReadLine());
		}
		
		n = Convert.ToInt32(Console.ReadLine());
		string[] stringArray = new string[n];
		for (int i = 0; i < n; i++)
		{
			stringArray[i] = Console.ReadLine();
		}
		
		PrintArray<Int32>(intArray);
		PrintArray<String>(stringArray);
	}
}

// Solution:

using System;

class Printer
{

	/**
	*    Name: PrintArray
	*    Print each element of the generic array on a new line. Do not return anything.
	*    @param A generic array
	**/
    // Write your code here
static void PrintArray<T>(T[] array)
    {
        foreach (T element in array)
        {
            Console.WriteLine(element);
        }
    }

    static void Main(string[] args)
	{
		int n = Convert.ToInt32(Console.ReadLine());
		int[] intArray = new int[n];
		for (int i = 0; i < n; i++)
		{
			intArray[i] = Convert.ToInt32(Console.ReadLine());
		}
		
		n = Convert.ToInt32(Console.ReadLine());
		string[] stringArray = new string[n];
		for (int i = 0; i < n; i++)
		{
			stringArray[i] = Console.ReadLine();
		}
		
		PrintArray<Int32>(intArray);
		PrintArray<String>(stringArray);
	}
