Rounds to nearest integer, or to specified number of digits (result = Math.Round(1.3768); = 1 or Math.Round(1.3768, 2); = 1.38)
What does the += combined operator mean?
x = x + 5 (x += 5;)
What does the -= combined operator mean?
x = x - 5 (x -= 5;)

x = x / 5 (x /= 5;)
What does the %= combined operator mean?
x = x % 5 (x %= 5;)
What does the const keyword do to a variable?
It is used to make a variable a constant that cannot be changed (const double GST_RATE = 0.05;)
What is a booleon value?

Console.WriteLine(isManager);
isManager = false;
Console.WriteLine(isManager);
})What is a char value?
A char is a value that is a single letter (staticvoidMain(string[] args)
{
charletter;
letter = 'A';
Console.WriteLine(letter);
letter = 'B';
Console.WriteLine(letter);
})What is Parsing?
