Yes, this is pretty sloppy. I probably should have used flags for some (or all?) of the error checking.
And some of the while loops probably could have been for loops, when I used a counter...except that you'd need to break out of the for loop when the user gets the correct answer and I don't know how to do that. How do you do that?
Also, is there a way to keep from having to create different variable names (example: for the user's answer or for their guess)?
So here's my sloppy code:
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
private static void greeting()
{
//Depending on the current time, print either "Good morning," "Good afternoon," or "Good evening"
DateTime time = new DateTime();
//get the current time
time = DateTime.Now;
//if it is past midnight but before noon, print "Good morning."
if (time.Hour >=0 && time.Hour < 12 )
{
Console.WriteLine("Good morning.");
}
//if it is past noon but before 6PM, print "Good afternoon."
else if (time.Hour >= 12 && time.Hour < 18)
{
Console.WriteLine("Good afternoon.");
}
//if it is past 6PM, print "Good evening."
else if (time.Hour >= 18)
{
Console.WriteLine("Good evening.");
}
}
//method to get answer from user, when asked if they want to know my name
public static void GetAns()
{
string ans = Console.ReadLine();
ans = ans.ToUpper();
if (ans == "Y")
{
Console.WriteLine("Okay. You asked. My name is Tammy.");
greeting();
}
else //if they enter anything other than Y or y, allow them to exit
{
Console.WriteLine("Okay. I will not tell you my name.");
greeting();
}
}
//method called when the user doesn't enter a valid number
public static void GuessError()
{
Console.WriteLine("You must enter a whole number greater than zero.");
}
static void Main(string[] args)
{ //initialize a new instance of the Random class
Random RandomClass = new Random();
//print greeting based on user's current time
greeting();
Console.WriteLine("Welcome to the game.\n");
Console.WriteLine("What shall I call you?");
//assign whatever they type to a property called name, which we will use throughout the game
string name = Console.ReadLine();
Console.WriteLine("Hello {0}!", name);
Console.WriteLine("Would you like to play a game? Type Y for yes or N for no.");
string answer = Console.ReadLine();
answer = answer.ToUpper();
if (answer == "Y")
{
Console.WriteLine("What do you want to play, {0}? Pick one: 1. Harder guessing game 2. Math game 3. Easy guessing game", name);

//if they didn't enter a number, return 0
