• 1. WAP to calcuate netsalary of an employee using a class name employee.
• 2. write c++ program to read data on N employee and compute net salary of each employee using class employee.
• 3. define a student class with other member data. decalre an array of 10 student , find the average of two better marks for each student.
• 4. WAP to implement function overloading fucntion ADD that returns complex number.      a. ADD(a,s1) where a is interger and s1 is complex.      b. ADD(s1,s2) where s1 and s2 both are complex.
• 5. WAP to implement hybrid inheritance
