Answer 1

string name = "", eman = "";
int nameLen;
nameLen = name.Length - 1;

while (nameLen >= 0)
{
eman = eman + name[nameLen];
nameLen--;
}

^I always forget about the playground. There it is in action, if you wish to check it out.

Basically, you reverse it by creating a secondary string variable that we'll store the new word in, and then just iterate backward through the first string array, capturing the letter in each index and storing it in the secondary string variable.

Hope that helps.

string name = "", eman = "";
int nameLen;

Console.Write("What's your name? \n");
name = Console.ReadLine();

nameLen = name.Length - 1;

while (nameLen >= 0)
{
eman = eman + name[nameLen];
nameLen--;
}

Console.WriteLine("Your name forward is {0}\n", name);
Console.WriteLine("Your name backward is {0}\n", eman);

Answer 3

When you're done, just assign the value of 'eman' to the variable 'name.'

string name = "", eman = "";
int nameLen;
nameLen = name.Length - 1;

while (nameLen >= 0)
{
eman = eman + name[nameLen];
nameLen--;
}
name = eman;

You don't have to continue using eman, it's just necessary to use it as a temporary variable so you can do the operations you need to do.
