Getting Started with C# Programming
Objective
The objective of this exercise is to develop a C# program that asks the user for a number and prints it in two different formats—first with spaces and then without—using both Console.Write() and formatted strings.
Write a C# program to ask the user for a number and display it four times in a row, separated with blank spaces, and then four times in the next row, with no separation. You must do it two times: first using Console.Write() and then using {0}.
Example C# Exercise
Show C# Code
// First and Last Name: John Doe
using System;
namespace NumberDisplay
{
class Program
{
// The Main method is where the program execution begins
static void Main(string[] args)
{
// Declare a variable to store the user's number
int number;
// Prompt the user to enter a number
Console.Write("Enter a number: ");
number = Convert.ToInt32(Console.ReadLine()); // Read and convert the input to an integer
// First method: Using Console.Write()
Console.Write("\nUsing Console.Write():\n");
Console.Write(number + " " + number + " " + number + " " + number); // Print with spaces
Console.Write("\n");
Console.Write(number + "" + number + "" + number + "" + number); // Print without spaces
Console.Write("\n\n");
// Second method: Using formatted strings with {0}
Console.WriteLine("Using {0} format:\n");
Console.WriteLine("{0} {0} {0} {0}", number); // Print with spaces
Console.WriteLine("{0}{0}{0}{0}", number); // Print without spaces
// Wait for the user to press a key before closing the console window
Console.ReadKey(); // Keeps the console open until a key is pressed
}
}
}
Output
Enter a number: 7
Using Console.Write():
7 7 7 7
7777
Using {0} format:
7 7 7 7
7777
