Answer to Question #243652 in C++ for xtian

Question

Write a program that will calculate and show bills of the Electric Company. The rates vary depending on whether the use is residential (R), commercial( C) , or industrial (I). Any other code should be treated as an error.
The program should accept the subscriber ID, Subscriber Name, his total electrical consumption in a month, and the code of the consumer type.

The rates are computed as follows:

R: 50 plus .50 per kwh used
C: 100 for the first 1000 kwh and 0.45 for each additional kwh
I: 180 for the first 1000 kwh and 0.75 for each additional kwh


please use ,
#include<stdio.h>
#include<conio.h>

and,
scanf:
printf
