Write a program that contains the following functions,

i. A function isVowel that takes in a character and returns true if it is a vowel and false otherwise

ii. A function that request from the user to enter in a sequence of characters, and outputs the number of vowels enetered.

2. An apartment complex contains possibly 60 apartments, rented out at possibly $500, when the apartment is at this rent price, it is fully occupied. Whenever there is an increase in the rent, possibly by $50, one renter moves out, reducing the occupied units by 1. The apartment complex spends $25 dollars to maintain each occupied unit. How many apartments should be rented to yield maximum profit for the complex. (Profit is calculated by subtracting the rent made from all occupied units from the cost it takes to maintain them).

Your program should input from the main the

Initial number of apartments the complex has

The rent price that has every apartment occupied

Your program should input from the function

The increase in rent that results in an unoccupied apartment

The amount it takes to maintain each occupied apartment

Your program should contain just one function where all calculations are done and output in the main the number of occupied apartments, it takes to yield maximum profit along with the value of the profit.

3) Write a program that contains the following functions (There are 25 numbers contained in a file)

A function to;

Determine and output the amount of even numbers

Determine and output the amount of odd numbers

Determine and output the amount of positive numbers

Determine and output the amount of negative numbers

Determine and output the number of zeros

Determine and output the sum of all 25 numbers

Use appropriate function calls in the main function. (Note: Negative numbers can also be odd and even)

Create the file and use the following numbers

0 2 -12 15 0 -7 -1 28 123 14 -863 17

11 -189 0 1283 290 -120 151 -63 13 230 0 -77 -2
