C++ style cin console-based input for C# developers

Nakov.IO.Cin is a console-based input parser for C#, which reads numbers and text in the C++ cin / cout / iostream style.

For example, in C++ we can read two integers using this code:

int x, y;
cin >> x >> y;

With Nakov.IO.Cin we can write the same code in C# like this:

int x = Cin.NextInt();
int y = Cin.NextInt();


Like in C++, the whitespace will be skipped so users can enter the input numbers on the same line, separated by spaces, or on separate lines.

Nakov.IO.Cin supports reading int, double, decimal and string tokens.


In this example we read two integers in C++:

int rows, cols;
cin >> rows >> cols;

In C# we can read two integers (using tuples) like this:

(int rows, int cols) = (Cin.NextInt(), Cin.NextInt());

Another C++ example:

#include <iostream>
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] << ' ';

The corresponding C# code:

using System;
using Nakov.IO;
public class EnterNumbers
    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

This is a more-detailed example how to use the Nakov.IO.Cin class:

using System;
using Nakov.IO; // See

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();

        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:
Enter your age:         25
Name: Albert Einstein, Age: 25
x=10, y=20
Enter a positive integer number N:
Enter N decimal numbers separated by a space: 10  30 40

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.
