33,235 Points"End of file" error
Hi. I'm not sure what I've done but I get an error message when trying to run my program:
using System; //Using directive: avoids repeating "System".
namespace Treehouse.FitnessFrog
{
class Program
{
static void Main()
{
run runningTotal = 0.0;
while (true) {
// Prompt the user for minutes exercised
Console.Write("Enter how many minutes you exercised or type \"quit\" to exit: "); //Print text to screen, keeps cursor at end of line after colon.
// Write: method name.
// Console: name of class that contains method.
// System: namespace that contains class.
// Namespace.ClassName.MethodName(parameterType parameterName);
var entry = Console.ReadLine(); //ReadLine reads one line at a time from the console.
if (entry.ToLower() == "quit")
{
break;
}
try
{
var minutes = double.Parse(entry);
if (minutes <= 0)
{
Console.WriteLine(minutes + " is not an acceptable value.");
continue;
}
else if (minutes <= 10)
{
Console.WriteLine("Better than nothing!");
}
else if (minutes <= 30)
{
Console.WriteLine("Way to go!");
}
else if (minutes <= 60)
{
Console.WriteLine("You must be a ninja in training!");
}
else
{
Console.WriteLine("Okay, now you're just showing off!");
}
runningTotal += minutes;
}
catch(FormatException)
{
Console.WriteLine("That is not valid input.");
continue;
}
// Add minutes exercised to total.
// Display total minutes exercised on-screen.
//WriteLine writes one line at a time to the console.
Console.WriteLine("You've entered " + runningTotal + " minutes."); //Plus operator concatenates strings.
// Repeat until user quits.
Console.WriteLine("Goodbye");
}
}
}
Error:
Program.cs(68,246): error CS1525: Unexpected symbol `end-of-file'
Compilation failed: 1 error(s), 0 warnings
Here's a snapshot I've taken: https://w.trhou.se/seepakgqxl
Thanks in advance for any help.

33,235 PointsHi Nipi and thanks for your input. I can see I'm one } short and that it's the while (true) one but I don't know where it's supposed to go. It's just that in the video, Jeremy cut and pasted a large chunk of code and that confused me. I was trying to work out which code he pasted and where. I think it would help if he posted the code in the Teacher's Notes.

using System; //Using directive: avoids repeating "System".
namespace Treehouse.FitnessFrog
{
class Program
{
static void Main()
{
var runningTotal = 0.0;
while (true) {
// Prompt the user for minutes exercised
Console.Write("Enter how many minutes you exercised or type \"quit\" to exit: ");
//Print text to screen, keeps cursor at end of line after colon.
// Write: method name.
// Console: name of class that contains method.
// System: namespace that contains class.
// Namespace.ClassName.MethodName(parameterType parameterName);
var entry = Console.ReadLine(); //ReadLine reads one line at a time from the console.
if (entry.ToLower() == "quit")
{
break;
}
try
{
var minutes = double.Parse(entry);
if (minutes <= 0)

Console.WriteLine(minutes + " is not an acceptable value.");

33,235 PointsHi Michael. Thanks for your help. I added a closing brace under Console.WriteLine("Goodbye");.
I can show you my Program as it is now:
using System; //Using directive: avoids repeating "System".
namespace Treehouse.FitnessFrog
{
class Program
{
static void Main()
{
run runningTotal = 0.0;
while (true)
{
// Prompt the user for minutes exercised
Console.Write("Enter how many minutes you exercised or type \"quit\" to exit: "); //Print text to screen, keeps cursor at end of line after colon.
// Write: method name.
// Console: name of class that contains method.
// System: namespace that contains class.
// Namespace.ClassName.MethodName(parameterType parameterName);
var entry = Console.ReadLine(); //ReadLine reads one line at a time from the console.
if (entry.ToLower() == "quit")
{
break;
}
try
{
var minutes = double.Parse(entry);
if (minutes <= 0)
{
Console.WriteLine(minutes + " is not an acceptable value.");
continue;
}
else if (minutes <= 10)
{
Console.WriteLine("Better than nothing!");
}
else if (minutes <= 30)
{
Console.WriteLine("Way to go!");
}
else if (minutes <= 60)
{
Console.WriteLine("You must be a ninja in training!");
}
else
{
Console.WriteLine("Okay, now you're just showing off!");
}
runningTotal += minutes;
}
catch(FormatException)
{
Console.WriteLine("That is not valid input.");
continue;
}
// Add minutes exercised to total.
// Display total minutes exercised on-screen.
//WriteLine writes one line at a time to the console.
Console.WriteLine("You've entered " + runningTotal + " minutes."); //Plus operator concatenates strings.
// Repeat until user quits.
Console.WriteLine("Goodbye");
}
}
}
}
I typed in mcs Program.cs in the console and I got:
Program.cs(9,9): error CS0246: The type or namespace name `run' could not be found. Are you m
issing an assembly reference?
Program.cs(50,11): error CS0841: A local variable `runningTotal' cannot be used before it is
declared
Program.cs(64,49): error CS0841: A local variable `runningTotal' cannot be used before it is
declared
I then typed in mono Program.exe and yet the program worked fine. I'm a bit miffed about the error messages that arose from my mcs Program.cs command.
Thanks. :)

Maybe i don't know much about C# syntax but,
Why were you declaring a variable with 'run' instead of 'var'?
The program doesn't seems to understand. The error explicitly says so.
