namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
string input = Console.ReadLine();//this is correct, good work
string output;//when you declare the variable here, accessibility of this variable is high, from here
if (input == "quit")
{
output = "Goodbye.";//Now that the output is declared, you cant declare here again, so I take off the string part
}
else
{
output = "You entered " + input + ".";//here too, I take the string part, otherwise, am double doing
}
Console.WriteLine(output);
//till here, the output variable could be accessed
}
}

namespace Treehouse.CodeChallenges

class Program
{
static void Main()
{
input = Console.ReadLine(); //variable being used without declaring, so you will need the variable type in front
if (input == "quit")
{
string output = "Goodbye.";//this is about variable scoping, string is only within this blocks
}
else
{
string output = "You entered " + input + ".";//again variable scoping, string is only available within the blocks
}
Console.WriteLine(output);// given, it was declared, in those blocks, it cannot be used here, the output
//better idea would be declare the output variable just below, where input is to be declared
//then you need not have declare the variable output, at, if and else
}
