C++ Programming Exercise:
The population of 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 = 5,000, growth rate of town A = 4%, population of town B = 8,000, and growth rate of town B = 2%.)
Need help with the code for this question:
Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
For example, it should output the individual digits of:
3456 as 3 4 5 6
8030 as 8 0 3 0
2345526 as 2 3 4 5 5 2 6
4000 as 4 0 0 0
-2345 as 2 3 4 5

Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices: 1. Sum of their square 2. Product of their square root 3. Square of their product The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping. Note: 1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit. 2. If the user chooses arithmetic operation No.2, format the output to three decimal placesarrow_forward

- Need Python code: Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.

SPECIFICATIONS: • The program will ask the user to choose whether to compute for the equivalent resistance of a series or parallel combination. • The user will input three resistance values R1, R2, and R3 in ohms. • The program will provide an output of equivalent resistance in series (Rs) or parallel (Rp). • You may only use the codes that we studied in our lectures. • All lines of codes should have a comment. To recall, the formula for solving the resistance for a purely series and purely parallel circuit are: a. Series Circuit: R1 120 ohms R2 Vs 100 V Rs = R7 = R1 + R2 + R3 + …+ Rn ... 30 ohms R3 50 ohms b. Parallel Circuit: 1 1 1 + R1' R2 ' R3 1 1 1 ...

You must have the maximum amount of higher denominations possible before allowing for lower denominations. For example, If your change is $18.88, You must have One Ten-dollar bill, One Five-dollar bill, Three singles, Three quarters, One dime and three pennies.

- A. Write a program that asks the user to enter a number of seconds.• There are 86400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86400, the program should display the number of days in that many seconds.• There are 3600 seconds in an hour. If the number of seconds entered by the user is less than 86400, but is greater than or equal to 3600, the program should display the number of hours in that many seconds.• There are 60 seconds in a minute. If the number of seconds entered by the user is less than 3600, but is greater than or equal to 60, the program should display the number of minutes in that many seconds.B.

The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format, and should calculate and print the total of yesterday's receipts. The program should use the function calculate Charges to determine the charge for each customer.arrow_forwardPlease can you type and execute all four programs and give output for all the programs.arrow_forward
