Let’s handle today arithmetic operators. I always try to explain as easy as possible.
= NOT Not equality, it is assigment
Math operators is + – * /
Addition assigment
total = total + 5;
total += 5;
Increment operator i++;
Decrement operator i–;
Beware of order of precedence (use parenthesis)
Beware of down casting (you will lose precision)
Beware of overflow (use bigger types)
To make overflow throw an exception
checked{
/some arithmetic operation that could potentially overflow
}
