Nakov.IO.Cin: the C# console input working as `cin` in C++
==========================================================
`Nakov.IO.Cin` is a console-based input reader for C#, which reads numbers and text in the C++ `cin` / `cout` / `iostream` style.
Install the NuGet Package
-------------------------
First, install the NuGet package [`Nakov.IO.Cin`](https://www.nuget.org/packages/Nakov.IO.Cin):
```
Install-Package Nakov.IO.Cin
```
Now you are ready to translate C++ `cin` / `cout` / `iostream` code to C#.
Sample C++ Code
---------------
```cpp
#include
using namespace std;
int main()
{
int n;
cin >> n;
int* numbers = new int[n];
for (int i = 0; i < n; i++)
cin >> numbers[i];
for (int i = 0; i < n; i++)
cout << numbers[i] << ' ';
}
```
Corresponsing C# Code
---------------------
```cs
using System;
using Nakov.IO; // see http://www.nakov.com/tags/cin
public class EnteringNumbers
{
static void Main()
{
int n = Cin.NextInt();
int[] numbers = new int[n];
for (int i = 0; i < n; i++)
numbers[i] = Cin.NextInt();
for (int i = 0; i < n; i++)
Console.Write(numbers[i] + " ");
}
}
```
More Detailed Example
---------------------
```cs
using System;
using Nakov.IO; // See http://www.nakov.com/tags/cin
public class CinExample
{
static void Main()
{
Console.Write("Enter your name: ");
string name = Console.ReadLine();
Console.Write("Enter two integers x and y separated by whitespace: ");
// cin >> x >> y;
int x = Cin.NextInt();
double y = Cin.NextDouble();
Console.Write("Enter your age: ");
int age = int.Parse(Console.ReadLine());
Console.WriteLine("Name: {0}, Age: {1}", name, age);
Console.WriteLine("x={0}, y={1}", x, y);
Console.Write("Enter a positive integer number N: ");
// cin >> n;
int n = Cin.NextInt();
Console.Write("Enter N decimal numbers separated by a space: ");
decimal[] numbers = new decimal[n];
for (int i = 0; i < n; i++)
{
// cin >> numbers[i];
numbers[i] = Cin.NextDecimal();
}
Array.Sort(numbers);
Console.WriteLine("The numbers in ascending order: {0}",
string.Join(' ', numbers));
Console.Write("Enter two strings seperated by a space: ");
// cin >> firstStr >> secondStr;
string firstStr = Cin.NextToken();
string secondStr = Cin.NextToken();
Console.WriteLine("First str={0}", firstStr);
Console.WriteLine("Second str={0}", secondStr);
}
}
```
This is a sample **input and output** from the above example:
```
Enter your name: Albert Einstein
Enter two integers x and y separated by whitespace:
10
20
Enter your age: 25
Name: Albert Einstein, Age: 25
x=10, y=20
Enter a positive integer number N:
5
Enter N decimal numbers separated by a space: 10 30 40
50
20
The numbers in ascending order: 10 20 30 40 50
Enter two strings seperated by a space:
Visual Studio
First str=Visual
Second str=Studio
```
Note that input numbers and string tokens can be separated by single space, by a new line or by a sequence of white space characters.
