advantage of passing parameters

1. a. What is an advantage of passing parameters by value as opposed to passing them by reference?

 

b. What is an advantage of passing parameters by reference as opposed to passing them by value?

 

2. What ambiguity exists in the statement

 

X ←3 + 2 X 5

 

3. Suppose a small company has five employees and is planning to increase the number to six.

 

Moreover, suppose one of the company’s programs contained the following assignment statements.

 

DailySalary = TotalSal/5;

 

AvgSalary = TotalSal/5;

 

DailySales = TotalSales/5;

 

AvgSales = TotalSales/5;

 

How would the task of updating the program be simplified if the program had originally been written using constants named NumberOfEmp and WorkWeek (both set to the value 5) so that the assignment statements could be expressed as

 

DailySalary = TotalSal/DaysWk;

 

AvgSalary = TotalSal/NumEmpl;

 

DailySales = TotalSales/DaysWk;

AvgSales = TotalSales/NumEmpl
