Source code example
using System;
namespace GuessTheNumber
{
class Program
{
static void Main()
{
Console.WriteLine("iNetTutor.com");
Console.WriteLine("Welcome to the Guess the Number game!");
// Generate a random number between 1 and 100
Random random = new Random();
int targetNumber = random.Next(1, 101);
// Initialize user guess and attempts
int userGuess = 0;
int attempts = 0;
// Start the guessing loop
while (userGuess != targetNumber)
{
// Prompt user for input
Console.Write("Enter your guess (between 1 and 100): ");
// Validate and parse user input
if (int.TryParse(Console.ReadLine(), out userGuess))
{
// Provide hints based on user's guess
if (userGuess < targetNumber)
{
Console.WriteLine("Too low. Try again!");
}
else if (userGuess > targetNumber)
{
Console.WriteLine("Too high. Try again!");
}
// Increment attempts
attempts++;
}
else
{
Console.WriteLine("Invalid input. Please enter a valid number.");
}
}
// Display success message
Console.WriteLine($"Congratulations! You guessed the number {targetNumber} in {attempts} attempts.");
Console.WriteLine("Please press any key in the keyboard to close the console.");
Console.ReadKey();
}
}
}
Explanation
The provided source code is a C# program that implements a “Guess the Number” game. Let’s go through the code and understand how it works.
Program Structure
The program is a console application with a single class named Program. It contains a Main method, which serves as the entry point of the program.
Game Setup
The program starts by displaying the messages “iNetTutor.com” and “Welcome to the Guess the Number game!” to the console.
Next, it generates a random number between 1 and 100 using the Random class. The generated number is stored in the targetNumber variable.
The program also initializes two variables: userGuess to store the user’s guess and attempts to keep track of the number of attempts made by the user.
Guessing Loop
The program enters a while loop that continues until the user’s guess matches the target number. Inside the loop, the program prompts the user to enter their guess by displaying the message “Enter your guess (between 1 and 100): “.
The user’s input is then read using the Console.ReadLine method and stored in the userGuess variable. The program validates the user’s input by using int.TryParse to check if the input can be successfully parsed as an integer. If the input is a valid number, the program proceeds to provide hints based on the user’s guess.
If the user’s guess is lower than the target number, the program displays the message “Too low. Try again!”. If the guess is higher, the program displays “Too high. Try again!”. In both cases, the attempts variable is incremented.
If the user’s input is not a valid number, the program displays the message “Invalid input. Please enter a valid number.”
Game Completion
Once the user’s guess matches the target number, the program exits the while loop. It displays a success message using string interpolation to include the target number and the number of attempts made by the user.
Finally, the program prompts the user to press any key to close the console using the Console.ReadKey method.
Example Execution
Here’s an example execution of the program:
iNetTutor.com Welcome to the Guess the Number game! Enter your guess (between 1 and 100): 50 Too low. Try again! Enter your guess (between 1 and 100): 75 Too high. Try again! Enter your guess (between 1 and 100): 63 Too low. Try again! Enter your guess (between 1 and 100): 70 Too high. Try again! Enter your guess (between 1 and 100): 67 Congratulations! You guessed the number 67 in 5 attempts. Please press any key on the keyboard to close the console.
