Write a C program to input electricity unit charges and calculate total electricity bill by using the switch statement according to the given condition:
For the first 50 units Rs. 0.50/unit
For the next 100 units Rs. 0.75/unit
For the next 100 units Rs. 1.20/unit
For unit above 250 Rs. 1.50/unit
An additional surcharge of 20% is added to the bill.

Output
enter the number of units you consumed
100
your total bill is Rs 75
