Question

E2a: Create a class called Employee that includes three pieces of information as data members---a first name (char array), last name (char array) and a monthly salary (integer). Your class should have a constructor that initializes the three data members. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10 percent raise and display each Employee’s yearly salary again.

Sample output:

Exployee 1: Bob Jones; Year ly Salary: 34500 Employee 2: Susan Baker: Yearly Salary: 37800 Increasing erployee salaries by 10% Eployee 1: Bob Jones; Year ly Salary: 37944 Eployee 2: Susan Baker: Yearly Salary: 41580
