Write a program to store consumer number and number of calls and calculate telephone bill accordin to condition

Take Customer number and no. of calls from user.

Calculate Bill as follows..

If number of calls <=100 : Free

Number of calls >=200 <=300 : 1.40 per call on over 100

Number of calls >=300 <=400 : 140+1.60 per call on over 200

Number of calls >=300 <=400 : 300+1.80 per call on over 300

Number of calls >=400 : 480+2.10 per call on over 400

And Fixed monthly rental: RS 100

And generate bill.
