QUESTION 7
Given:
int myvar=3;
I want the expression to be true if myvar is equal to 2 or myvar is equal to 3. What is wrong with the following expression?
myvar == 2 || == 3
The expression is fine, there is nothing wrong.
The expression is asking if myvar is 2 and myvar is 3. But myvar can't be two numbers at once!
> and < should be used, not ==
The == is a binary operator (like the addition operator, +, is a binary operator). That means there has to be something on both sides of the operator.
