Define a struct called Work that has the components type of type string, hours of type

integer, fee of type float for working for one hour;

Define a class called Worker that has the private members name of type string,

numberOfJobs of type integer, $p$ a pointer of type Work, cost of type float, and findCost $()$ a

function to find the cost of all jobs. The class has the public members $,$ print $,$ a default

parametrized constructor, a destructor, and a copy constructor.

Overload the extraction $$ operator, the insertion $$ operator, the assignment $=$ operator,

and the pre$-$increment operator $++$ as a member function of the class. The pre$-$increment

operator adds $1$ to the numberOfJobs data member, so information of one more job should be

entered and the cost is recalculated.

Implement all functions of the class, enforcing the least privileged principle.

The following driver produces the given sample of input $/$ output:

Sample input $/$ output:

Omar Ali did $3$ jobs at a cost $600$

Enter the job type, hours, and fee for $4$ jobs:

Carpting $320\mathrm{.}5$

Painting $725\mathrm{.}0$

Solering $135\mathrm{.}0$

Carpentering $235\mathrm{.}5$

Ali Omar did $4$ jobs at a cost $342\mathrm{.}5$

Enter one more job type, hours, and fee:

Glassing $450\mathrm{.}0$
