     7. What  is  the  purpose  of  the  term  'return type' in 
        a function definition?
    
        a) To specify the data type of the function.
    
        b) To specify the type  of data the function returns.
    
        c) to specify the type of variables used as parameters.
    
        d) To specify the type of variables passed to the
    	 function.
    
     8. Which one of the following best describes a function 
        call?

           and the function's storage class.
    
        b) Defines the operation a function must perform.
    
        c) Identifies the function parameters.
    
        d) States the name of the function and passes

           name and parameters to be used in processing.
    
        c) Calls a predefined function and passes the necessary
    	 arguments.
    
        d) Tells the compiler which function you are using.
