What s the different between Console.Write("H") and Console.Write( H ) in C#?
One uses a string overload (the string "H"), one uses a char overload (the char H ). Both output the character H to the stream defined in Console.Out without adding a newline.
The difference is that in the first call, you re passing a string and in the second call, you re passing a char. Practically speaking, those two calls are equivalent.
H is a single character (char) whereas "H" can have more than one character (string).
