1. Write a program to calculate the monthly cell phone bill based on the following plan
   1. Minimum cost of $100 for up to 100 texts
   2. An additional $0.60 per text for the next 50 texts after the first 100
   3. An additional $0.50 per text for the next 50 texts after the first 150
   4. An additional $0.40 for any texts after the first 200 texts.

Your program will process an integer representing the number of texts for a given month, and print the result that is the bill for those texts. Use what we know about mathematical operations, if else statements and anything else we have learned to do this. C++
