    3 if (num > 10) {
    4 int half = num / 2;
    5 System.out.println(“Half num = “ + half);
    6 } else {
    7 System.out.println(num);
    8 }
    9 }

    I'm confused about:
    the line numbers were variable scope is visible
    I don't see a variable named: scope

    the actual and formal parameters in the program.
    Ask google. That sounds like something from a textbook or that a professor would use.

    The variables used in a program are always declared. The location you declare a variable controls its “visibility” and role in a program. The area where a variable is declared and can be accessed is referred to as its scope"

    What I need to know is were are the variables in my program??

    where are the variables in my program
    Are you asking about what tokens in your program are variables?
    A variable is given a section of memory that holds a value while the program executes.
    For example, the following statement define a variable to hold an int value:
       int theVar = 123;// define an int variable and give it an initial value of 123

    For an exercise, list the names of the variables in the program you posted.

    Do you know what a variable is and what it is used for?

    For a full and better explanation ask google for a definition of a computer program variable.
