To store a value into a variable, you use the assignment operator (an equals-sign character).
General Form
name = expression
This means, "calculate the expression and store its result into the variable, replacing the variable's previous contents."
Examples
poleCount = 300
levelName = 'Lighting Fixtures'
isImageReversed = false
As a convenience, you can declare a new variable and store a value into it at the same time.
Example
int cardsInDeck = 52
