Here, we have a basic program example to calculate the electricity bill using different languages. The charge are as follow : Unit  Charge/unit

upto 199   @1.20

200 and above but less than 400  @1.50

400 and above but less than 600  @1.80

600 and above    @2.00

If bill exceeds Rs. 400 then a surcharge of 15% will be charged and the minimum bill should be of Rs. 100/-

This program is created in c language, c++, Java, and Python.
