A bank in your town updates its customers’ accounts at the end of each month. The bank offers two types of accounts: savings and checking. Every customer must maintain a minimum balance. If a customer’s balance falls below the minimum balance, there is a service charge of $10.00 for savings accounts and $25.00 for checking accounts. If the balance at the end of the month is at least the minimum balance, the account receives interest as follows: * Savings accounts receive 4% interest. * Checking accounts with balances of up to $5,000 more than the minimum balance receive 3% interest; otherwise, the interest is 5%. Write a program that reads a customer’s account number (int type), account type (char) s for savings, c for checking, minimum balance that the account should maintain, and current balance.

Write a C program that follows these guidelines:

1. Include the header file named tools.h. It will include all other headers you need.
2. In main(), declare a character array that is 26 slots long.
3. Print a title on the first line of the output: “Program 1: A List Of Letters Used”. Print your name or names on the second line of the output and leave a blank line after that.
4. Write an input loop, and repeat it until the sentinel character (#) appears:
5. (a) Read a character from the keyboard.
6. (b) Terminate the input loop when the user types a #.
7. (c) Otherwise, if the letter is not alphabetic, reject it and continue at the top of the loop.
8. (d) If the letter is upper-case, change it to lower case.
9. (e) Now you have a lower-case letter; find out if it has already been entered by comparing it to each of the letters you have saved in your array. If it is a duplicate, reject it and continue at the top of the loop.
10. (f) Now you have a NEW lower-case letter. Store it in the first unused slot in your char array

Design a pseucode and flowchart for the question The population of a town A is less than the population of town B. However, the population of town A is growing faster than the population of town B. Write a program that prompts the user to enter the population and growth rate of each town. The program outputs after how many years the population of town A will be greater than or equal to the population of town B and the populations of both the towns at that time. (A sample input is: Population of town A = 5000, growth rate of town A = 4%, population of town B = 8000, and growth rate of town B = 2%.)
