An electricity supply company calculates the customer monthly bill amounts. Draw a Flow chart and a Pascal Program to input the bill amounts of 10 electricity bills and output total amount of all the electricity bills.
program SumBillAmount;

end;
write('Total Bill Amount of all the bill is =');
writeln(Tot);
readln;
