2.b. Define a class worker with the following specification. 4

Private member of class worker:

wname	25characters
hrwrk,wgrate	float (hours worked and wagerate per hour)
totwage	float(hrwrk*wgrate)
cakcwg()	A function to find hrwrk*wgrate with float
return type

Public members of class worker: In_data( ): A function to accept values for wno, wname, hrrwrk, wgrate and invoke calcwg( ) to calculate totpay. Out_data( ): A function to display all the data members on the screen you should give definitions of functions.

class worker
{
char wname[25];
float hrwrk,wgrate;
float totwage;
float cakcwg( )
{
return hrwrk*wgrate;
}
public: void In_data( )
{
cout<<”\nEnter Worker number,name,hours worked and wage rate”;
cin>>wno; gets(wname);
cin>>hrwrk>>wgrate;
calcwg( );
}
void Out_data( )
{
cout<<”\nThe Worker Number: “<<wno;
cout<<”\nThe Name of the worker: “<<wname;
cout<<”\nNumber of hours worked by the worker: “<<hrwrk;
cout<<”\nThe Wage Rate of the Worker: “<<wgrate;
cout<<”\nThe total wages of the worker: “<<totwage;
