Answer»

class Ele_Bill

{

char Cname[20];

long Pnumber;

int No_of_units;

float Amount;

void Calc_Amount( );

public:

void Accept();

void Display();

};

void Ele_Bill : : Calc_Amount( )

{

if(No_of_units<=50)

{

Amount=0;

}

else if(No_of_units<=150)

{

Amount=(No_of_units-50)*0.80;

}

else if(No_of_units<=350)

{

Amount=80+(No_of_units-150)*1.00;

}

else

{

Amount=80+200+(No_of_units-350)*1.20;

}

void Ele_Bill :: Accept( )

{

gets(Cname);

cin>Pnumber>>No_of_units;

Calc_Amount( );

}

void Ele_Bill :: Display( )

{

cout<<Cname<<Pnumber<<No_of_units<<Amount;

}
