Fill in the letter of most appropriate category based on how the shaded variable is used in context. Choices are: $I=$Input Capture; $E=$ Expression$-$Result; $C=$ Counter; $A=$ Accumulator.

An input$-$capture variable is used to store a value typed in by the end user and captured with cin. An expression$-$result variable is a variable used to store the result of evaluating an expression to the right of the $=$ sign. An accumulator variable is used to increase or decrease a variable's value by an amount that can vary; a counter variable is similar to an accumulator, but the amount it is always increased or decreased by the same amount, usually a whole number, like $1.$ This is Java.
